Homework Statement


How much 4.00M of HCl is required to make 100ml of 0.400M HCl?

Homework Equations


M1V1 = M2V2

The Attempt at a Solution


Its (4.00M)*(xL) = (0.400M)(0.100L)
I think its 0.005L but the possible answer (multiple choice) say otherwise...

This equation is setup correctly.

But the number you get is incorrect. Try re-doing the calculation.

They ask you how much of a solution is required to make (100 ml of) a solution a tenth as concentrated and you need a formula?

The question should say How much 4.00M of HCl is required to make 100ml of 0.200M HCl?

Oops typo, I meant to say (4.00M)*(xL) = (0.200M)*(0.100L)

Must be a mistake in the test (assuming you finally listed the problem and answers right).
