Find the volume of 5.74 grams of NO2 (Hint: use two factors)

Answers

Answer:

1.2 cm^3

Explanation:

5.74 grams of a something occupies a volume of 1.2 cm^3 .

The sample contains 1. 02 mol S. To calculate the mole ratios of the elements, you will divide each molar amount by 1. 02 mol. Calculate the mole ratios of the elements in the compound. Round each ratio to the nearest whole number. Mole ratio of H:S = mole ratio of S:S = mole ratio of O:S =.

A sample of an unknown gas occupies 5.51 L at 1.31 atm. What pressure would thisgas exert in a 0.520 L container if the temperature is held constant?

Answers

Answer:

P₂ = 13.9 atm (3 sig. figs.)

Explanation:

The pressure (P), Volume (V) relationship with Temperature (T) & mass (n) held constant is an inverse proportionality. That is Boyles Law ...

P ∝ 1/V => P = k/V => k = P·V

For two pressure-volume conditions, the proportionality constant (k) remains constant where k₁ = k₂ and P₁·V₁ = P₂·V₂ => P₂ = P₁·V₁/V₂

Given:

P₁ = 1.31 atm.

V₁ = 5.51 L

P₂ = ?

V₂ = 0.520 L

V₂ = (1.31 atm)(5.51L)/(0.520L) = 13.88096154 atm (calc. ans.) = 13.9 atm (3 sig. figs.)

When you are standing on the ground, you have no trouble jumping 4 feet horizontally. If you are standing in a canoe, however, and you need to jump 4 feet to reach the pier, you will surely fall into the lake. Why is it that you cannot jump 4 feet out of a canoe when you can easily do this when on land?

calculate the moles and Molecules presents in ammonia present in 5.6dm3
of its volume STP?

​

Answers

Answer: 0.25 moles NH3

              1.51x10^23 molecules NH3

Explanation:

5.6dm3 (cubic decimeters)

1 dm^3 = 1 liter

We have 5.6L of ammonia (NH3 gas) at STP.  All gases at STP occupy 22.4 liters/mole.  Use this information as a conversion factor:

(22.4 L NH3)/(mole NH3)

Therefore:

(5.6L NH3)/(22.4 L NH3)/(mole NH3) = 0.25 moles NH3

Use Avogadro's number to convert moles to particles/molecules

(0.25 moles NH3)*(6.02x10^23 molecules/mole) = 1.51x10^23 molecules NH3
