Question

(Help would be greatly appreciated) What is the molarity of 3 moles of HCl in 3 L of water?

1. 3M
2. 1M
3. 6M
4. 9M

Answer 1

1 M

Step-by-step explanation:

Molarity is moles per liter (mol/L).

You have 3 moles of HCl in 3 L of water. Divide the two values.

(3 mol)/(3 L)

= 1 mol/L

= 1 M
