Question

Calculate Molarity of a solution with 3 moles of compound A in 1L of solution.

• A. 1 M
• B. 3 M
• C. 1/3M
• D. 0.3 M

Answer 1

The correct option is B

3 M

We know that,

Molarity = $\frac{\text{No of moles of solute}}{\text{No. of litres of solution}}$

No of moles of compound A is given as 3 and the volume of solution is 1 litre.
$\therefore$ Molarity = $\frac{3}{1}=3Molar$
