Question

a solution contains 2.1 moles of HCl and has a molarity of 6.00 M what volume of the solution occupy.

Answer 1

Use the formula C = n / V

We are given the moles, n = 2.1
And the molarity, C = 6

Rearrange the formula with V as the subject:

V = n / C

Sub in your values,

V = 2.1 / 6
   = 0.35 L

Hope this helped! :)
