Answer to Question #107996 in General Chemistry for Jeo

Question

Describe how you would prepare a 250.0 mL solution of 2.5 M H2SO4 from a 12.0 M stock solution. Be sure to include the
amount of stock solution required in order to prepare

Answer 1

$$n(H_2SO_4) = cV = 2.5M*0.250L = 0.625mol$$

$$V(H_2SO_4)_1 = n/c = 0.625mol/12.0M = 0.0521L = 52.1mL$$

52.1 mL of the initial solution with a concentration of 12.0 M must be brought with water to a volume of 250.0 mL
