8 g of sugar was dissolved in 82 ml of water, what is the mass fraction. substances in the resulting solution.

8 g of sugar was dissolved in 82 ml of water, what is the mass fraction. substances in the resulting solution

1. Since the density of water is 1 g / ml, then:

m (water) = V (water) * ρ (water) = 82 ml * 1 g / ml = 82 g

2. Calculate the mass of the solution:

m (solution) = m (water) + m (sugar) = 82 g + 8 g = 90 g

3. Determine the mass fraction of sugar in the resulting solution:

ω (sugar) = (m (sugar) / m (solution)) * 100% = (8 g / 90 g) * 100% = 8.89%.

Answer: the mass fraction of sugar in the resulting solution is 8.89%.
