Question

What is the molarity of a 9.79 L solution that contains 0.400 mol HCI

Answer 1

Answer:

0.041 M

Explanation:

The molarity of a solution when given the number of moles the substance and it's volume can be found by using the formula

$c = \frac{n}{v}$

n is the number of moles

v is the volume in L

We have

$c = \frac{0.4}{9.79} \\ = 0.04058...$

We have the final answer as

0.041 M
