Question

What is the %v/v of a solution made from 141.1 g of ethylene glycol (density is 1.11 g/mL) in water (density 1.00 g/mL) to form a total volume of 500.0 mL? You may assume the density of ethylene glycol does not change in the solution.

Answer 1

mass = volume x density or volume = mass/density
v ethyleneglycol = m/d = 141.1/1.11 = 127.1 mL
total volume = 500 mL.
% v/v ethylene glycol = (127.1 mL/500 m)*100
