Question

1. A student attempts to make a saline solution by adding salt to water. How much water did
they have if the solution is 0.90% m/v and they used 1.0g of salt?
mass of solute

(Please show work or how you got the answer)

Thanks!!

Answer 1

111.1 mL of water

Explanation:

Weight per volume concentration (w/v %) is defined as

weight per volume concentration = (mass of solute (g) / volume of solution (mL)) × 100

volume of solution = (mass of solute × 100) / weight per volume concentration

volume of solution = (1 × 100) / 0.9 = 111.1 mL

volume of water = volume of solution = 111.1 mL
