How many milliliters of a 9.0 M H₂SO₄ solution are needed to make 0.35 L of a 3.5 M solution?

Question

Quizplus · Accepted Answer

We can use the formula:
C1V1 = C2V2
where C1 and V1 are the concentration and volume of the original solution, and C2 and V2 are the concentration and volume of the final solution.
Plugging in the values:
C1 = 9.0 M
V1 = x (unknown)
C2 = 3.5 M
V2 = 0.35 L = 350 mL
Solving for V1:
C1V1 = C2V2
9.0x = 3.5(350)
x = 140 mL
Therefore, 140 mL of the 9.0 M solution are needed to make 0.35 L of a 3.5 M solution.
