Question

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

Answer 1

0.041 M

Step-by-step 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 = (n)/(v) \\`

n is the number of moles

v is the volume in L

We have

`c = (0.4)/(9.79) \\ = 0.04058...`

We have the final answer as

0.041 M
