Asolution containing 42% naoh by mass has a density of 1.30 g/ml. what mass, in kilograms, of naoh is in 6.00 l of this solution?

3.276 kg

Explanation:

By definition:

Density of solution =  mass of solution / volume of solution

mass of solution = density of solution * volume of solution

Density of solution: 1.30 g/ml = 1.30 kg/l

mass of the solution = 1.3 * 6.00 = 7.8 kg

By definition:

percent by mass = (mass of solute / mass of solution) *100

mass of solute = (percent by mass/100) * mass of solution

mass of solute = 42/100 * 7.8 = 3.276 kg
