Answer: 93.6 g.
Explanation of the solution to the problem: to solve this problem, you must use the following formula:
m (solution in-va) = m (solution) * w, where m (solution in-va) is the mass of the solute in grams, m (solution) is the mass of the solution in grams and w is the mass fraction solute in solution (in fractions). Substitute the values known from the condition and get:
m (solution in-va) = m (solution) * w = 520 * 0.18 = 93.6 g.
