Question

A solution has 500 mL and contains 0,5 moles of AlCl3. What is its molarity?

Answer 1

Answer:

The molarity is: 1 M

Explanation:

We define molarity as an amount of moles in 1000ml of solution (1 liter)

500ml---------0,5 moles AlCl3

1000ml------x= (1000ml  x 0,5 moles AlCl3)/500ml = 1 moles ACl3--> 1 M
