Question

White vinegar is a 5.0% by mass solution of acetic acid in water. If the density of white vinegar is 1.007 g/cm³

Answer 1

There is not a question here, but the concepts you need for related questions are that

density D = mass/volume = (mass of ascetic acid + mass of water) / volume of solution, so assume we have 1 cc of solution, which has a mass of 1.007 g. Then 0.05*1.007 g will be the mass of ascetic acid, and 0.95*1.007 g will be the mass of the water. Knowing g/cc of acetic acid C2H4O2 allows one to convert to moles/L = M (molarity).
