35 g of nitric acid was dissolved in 175 g of water. Find the mass fraction of acid in the resulting solution.

Given:

m (water) = 175 g

m (acid) = 35 g

Find:

w (solution) -?

1. Let’s find the mass of the resulting solution by the formula:

m (solution) = m (water) + m (acid) = 175 + 35 = 210 g

2. Let’s calculate the mass fraction of acid in the resulting solution using the formula:

w (solution) = m (acid) * 100% / m (solution) = 35 * 100/210 = 16.7%

Answer: 16.7%
