Question

With this information, we now need to calculate the volume in milliliters. We need to know how many mls a drop of oleic acid occupies using the density of 0. 895 g/ml and the number of drops of oleic acid solution used.

Answer 1

The molarity is the number of moles of acetic acid per liter of solution. To calculate the mole fraction of acetic acid in the solution, we need to know the number of moles of both acetic acid and water.

Step-by-step explanation:

A: The molarity is the number of moles of acetic acid per liter of solution. We can calculate the number of moles of acetic acid as its mass divided by its molar mass.

B: To calculate the mole fraction of acetic acid in the solution, we need to know the number of moles of both acetic acid and water. The number of moles of acetic acid is 0.0629 mol, as calculated in part (a). We know that 100.0 g of vinegar contains 3.78 g of acetic acid; hence the solution also contains (100.0 g - 3.78 g) = 96.2 g of water. We have
