Question

What is the mass-volume percent of a solution made by dissolving 89.95 g of NaOH in enough water to make 250.0 mL of solution?

Answer 1

The mass-volume percent of the solution is 35.98%.

Step-by-step explanation:

The mass-volume percent is a measure of the concentration of a solute in a solution, expressed as the mass of the solute divided by the volume of the solution, multiplied by 100%.

In this case, the mass of NaOH is given as 89.95 g, and the volume of the solution is given as 250.0 mL. To calculate the mass-volume percent, we divide the mass of NaOH by the volume of the solution and multiply by 100%.

Mass-volume percent = (mass of NaOH / volume of solution) x 100%

Plugging in the values, we get:

Mass-volume percent = (89.95 g / 250.0 mL) x 100% = 35.98%.
