10 grams of sodium chloride was dissolved in 90 grams of water. Calculate the mass fraction of the salt of the resulting solution.
1. Find the mass of sodium chloride solution by the formula:
m (solution) = m (water) + m (salt) = 90 g + 10 g = 100 g.
2. We calculate the mass fraction of salt in the resulting solution by the formula:
w (solution) = m (salt) * 100% / m (solution) = 10g * 100% / 100g = 10%.
