In a school’s laboratory, students require 50 point 0 milliliters of 2 point 5 0 cap m cap h sub 2 SO sub 4 for an experiment, but the only available stock solution of the acid has a concentration of 18 point 0 cap m What volume of the stock solution would they use to make the required solution? Use cap m sub i cap v sub i is equal to cap m sub f cap v sub f
A
0 point 9 0 0 millilitersUse the dilution equation MᵢVᵢ = MբVբ. Solving for the stock volume gives Vᵢ = (2.50 M × 50.0 mL) ÷ 18.0 M = 6.94 mL. They should use 6.94 milliliters of the stock solution, choice A.
