Answer:

7.224 × 10^28 atoms

Explanation:

The number of moles contained in a substance (n) can be calculated from this expression:

nA = n × 6.02 × 10^23 atoms

Where;

nA = number of atoms of substance

n = number of moles of substance

Avagadro's number or constant = 6.02 × 10^23 atoms

Using nA = n × 6.02 × 10^23 atoms

In this question, there are 1.2 x 10^5 moles of neon (N). The number of atoms (nA) is as follows:

nA of neon = 1.2 x 10^5 × 6.02 × 10^23

nA = 7.224 × 10^ (5 + 23)

nA = 7.224 × 10^28 atoms

The number of neon atoms in 1.2 x 10^5 is 7.224 × 10^28 atoms.

Answer:

No, It would be a unsaturated solution

Explanation:

The solubility of a compound gives us information about how a compound may dissolve or not in a determinate solvent.

In this case we have Z, which in 25 °C the solubility of this compound is 40g/100 mL water. This means that if we have 60 g of Z and try to dissolve it in 100 mL of water, only 40 g of Z will solve and the remaining 20 g will be in the water as precipitate or remaining solid.

Now if you just put 40 g of Z in 100 mL water, it will dissolve completely in water, and in this case, we have a saturated solution. A saturated solution is when you dissolve a determinated quantity of a solute in a determinated quantity of solvent, without remaining of solid or excess of solvent.

According to this explanation, we now have 120 g of Z. To make a saturated solution of Z with this quantity, well, let's do math. If 40 g dissolves in 100 mL, then 80 g would be 200 mL and 120 g would have to be 300 mL of water. But in this case, we have 450 mL of water, we have more than 300 mL, an excess of water, so, the 120 g will dissolve but it's dissolved in more than the needed quantity to be a saturated solution, therefore, we have an unsaturated solution of Z (more solvent than the needed).

Hope this helps.

Answer: The final temperature is 248.7 K

Explanation:

To calculate the final temperature of the system, we use the equation given by Gay lussac Law. This law states that pressure of the gas is directly proportional to the temperature of the gas at constant volume.

Mathematically,

[tex]\frac{P_1}{T_1}=\frac{P_2}{T_2}[/tex]

where,

[tex]P_1\text{ and }T_1[/tex] are the initial pressure and temperature of the gas.

[tex]P_2\text{ and }T_2[/tex] are the final pressure and temperature of the gas.

We are given:

[tex]P_1=951.72kPa\\T_1=653.34K\\P_2=362.29kPa\\T_2=?[/tex]

Putting values in above equation, we get:

[tex]\frac{951.72}{653.34}=\frac{362.29}{T_2}\\\\T_2=248.7K[/tex]

Thus the final temperature is 248.7 K

Explanation: i just did it, hope this helps :)

When one substance dissolves into another, a solution is formed.  A solution is a homogeneous mixture consisting of a solute dissolved into a solvent .  The solute is the substance that is being dissolved, while the solvent is the dissolving medium.  Solutions can be formed with many different types and forms of solutes and solvents.

Explanation:

solute are substance that dissolve in solvent

solvent are substance that dissolve solute

Answer:

1.213 g/mol

Explanation:

We are given that the molecular mass is 7.304 × 10²³ g.

From avogadro's number, we know that;

1 mole of a substance = 6.022 × 10²³ molecules

Thus;

Molar mass = molecular mass/avogadro's number = (7.304 × 10²³)/(6.022 × 10²³) = 1.213 g/mol

[tex]\boxed {\boxed {\sf A. \ 38.1 \%}}[/tex]

Explanation:

Percent yield is the ratio of the amount actually produced to how much could theoretically be produced. It is found using this formula:

[tex]\% \ yield = \frac{actual \ yield}{theoretical \ yield} *100[/tex]

For this reaction, the theoretical or expected yield is 325.0 grams. The actual yield is 123.8 grams.

[tex]\% \ yield = \frac{ 123.8 \ g }{325.0 \ g }*100[/tex]

Divide.

[tex]\% \ yield = 0.380923077 *100[/tex]

[tex]\% \ yield = 38.0923077[/tex]

Round to the nearest hundredth. The 9 in the hundredth place tells us to round the 0 to a 1 .

[tex]\% \ yield \approx 38.1[/tex]

The percent yield is about 38.1%

Answer:

38.1%

Answer:

14.02 x 10²⁴ molecules

Explanation:

To solve this problem we will use Avogadro's number: It relates to the number of molecules (or atoms) contained in 1 mol of any given substance:

Thus, 23.28 moles of water contain 14.02 x 10²⁴ molecules.

Answer:

Humdity would decrease hence temprature would do the same, hence tundra are called deserts at times.

Explanation:

If you keep on decreasing the temperature without changing the air's moisture content significantly, eventually you'll reach 100 percent relative humidity, and then water vapor will start to condense to form dew.

Dew Point. When the relative humidity reaches 100 percent, dew forms. Dew point refers to the temperature at which air reaches saturation by water molecules. Warmer air can hold more water molecules, and as that warm air cools, it loses water vapor in the form of condensation.

When relative humidity reaches 100 percent or is saturated, moisture will condense, meaning the water vapor changes to liquid-vapor. Thus, the saturation level of air is related to the air's temperature.
