Taking into account the definition of dilution, the molarity of the glucose in the diluted solution is 0.1 M.
DilutionWhen it is desired to prepare a less concentrated solution from a more concentrated one, it is called dilution.
Dilution is the process of reducing the concentration of solute in solution, which is accomplished by simply adding more solvent to the solution at the same amount of solute.
In a dilution the amount of solute does not change, but as more solvent is added, the concentration of the solute decreases, as the volume (and weight) of the solution increases.
A dilution is mathematically expressed as:
Ci×Vi = Cf×Vf
where
Ci: initial concentrationVi: initial volumeCf: final concentrationVf: final volumeFinal concentrationIn this case, you know:
Ci= 0.500 MVi= 10 mLCf= ?Vf= 50 mLReplacing in the definition of dilution:
0.500 M× 10 mL= Cf× 50 mL
Solving:
(0.500 M× 10 mL)÷ 50 mL= Cf
0.1 M= Cf
In summary, the molarity of the glucose in the diluted solution is 0.1 M.

9. What happens to the food in the mouth?
Answer:
The food gets soiled in the mouth.
Explanation:
The saliva in the mouth soils the food.
A pregnant woman, who is gravida 2 para 1, is being examined by the doctor. The doctor records on the chart that the woman has placenta previa, polyhydramnios, and preeclampsia. The doctor is sending her home on bed rest to prevent a spontaneous abortion. Define “gravida 2” and “para 1,” the diagnoses, and the phrase “spontaneous abortion.”
In your first post make sure that you are answering the question in the discussion question, your second post should be a response to a classmates post. Your response to your classmates post should be thoughtful and not just great job on your post, interact with your classmate. In this response to your classmate maybe discuss what you did and not know about these definitions.
gravida 2 para 1 means “pregnant woman 2” = number of pregnancies and “para 1” number of deliveries after 20 weeks, the diagnoses mean that she is at serious risk of having a miscarriage.
What are the complications of placenta previa?The main risk of placenta previa is causing premature birth and bleeding, which will harm the health of both mother and baby. In addition, placenta previa can also cause placental accreta, which is when the placenta is adhered to the wall of the uterus, making it difficult for it to come out at the time of delivery.
When is preeclampsia considered?Diagnosis of preeclampsia and eclampsia. The diagnosis of preeclampsia is suggested by symptoms or the presence of hypertension, defined as systolic blood pressure > 140 mmHg, diastolic blood pressure > 90 mmHg, or both.
What is the risk of polyhydramnios?It is associated with increased risk of premature contractions, premature rupture of membranes, maternal respiratory compromise, fetal malposition or death, and various problems during labor or delivery.
With this information, we can conclude that gravida 2 para 1 means “pregnant woman 2” = number of pregnancies and “para 1” number of deliveries after 20 weeks, the diagnoses mean that she is at serious risk of having a miscarriage.

10.0 g of table salt, NaCl, is dissolved in water to a total volume of 125.0 mL. What is the resulting molar concentration of the table salt?
Taking into account the definition of molarity, the molar concentration of the table salt is 1.368 [tex]\frac{moles}{liters}[/tex].
Definition of molarityMolar concentration or molarity is a measure of the concentration of a solute in a solution and indicates the number of moles of solute that are dissolved in a given volume.
The molarity of a solution is calculated by dividing the moles of solute by the volume of the solution:
[tex]molarity=\frac{number of moles}{volume}[/tex]
Molarity is expressed in units [tex]\frac{moles}{liters}[/tex].
Molar concentration of the table saltIn this case, you have:
number of moles= 10 g×[tex]\frac{1 mole}{58.45 g}[/tex]= 0.171 moles [being [tex]58.45\frac{g}{mole}[/tex] the molar mass of NaCl]volume= 125 mL= 0.125 L [being 1000 mL= 1 L]Replacing in the definition of molarity:
[tex]molarity=\frac{0.171 moles}{0.125 L}[/tex]
Solving:
molarity= 1.368 [tex]\frac{moles}{liters}[/tex]
Finally, the molar concentration of the table salt is 1.368 [tex]\frac{moles}{liters}[/tex].
