Question

A chemist needs 225 ml of 2.4 m hcl. What volume of 12 m hcl must be mixed with water to form this solution?

Answer 1

1125 mL

Step-by-step explanation:

This is very much like a math problem. You have to set it up as a proportion:

The setup "template" should be mL/m HCl.

`(225)/(2.4)=(x)/(12)`

Now, you cross multiply:

225*12 = 2.4*x

2700 = 2.4x

Divide:

x = 1125
