1. Mass fraction is found according to the following formula:

ω = m (substance) / m (solution) * 100%, where ω (omega) – mass fraction, m – mass.

2.m (substance) = 30g, m (solution) = 100g (by condition).

3. Substitute the values into the formula:

ω = 30/100 * 100% = 30%.

Answer: Mass fraction (ω) = 30%.
