Question

Calculate the molarity of 48.0 mL of 6.00 M H2SO4 diluted to 0.250 L .

Answer 1

Answer:

1.152 M.

Explanation:

• It is known that the no. of millimoles of a substance before dilution is equal to the no. of millimoles after dilution.

∴ (MV) before dilution = (MV) after dilution

before dilution: M = 6.0 M, V = 48.0 mL.

after dilution: M = ??? M, V = 0.25 L = 250.0 mL.

∴ M after dilution = (MV) before dilution/(V) after dilution = (6.0 M)(48.0 mL)/(250.0 mL) = 1.152 M.
