Question

What is the molarity of a solution that contains 1.1 moles of lithium in 0.5 liters of solution?

Answer 1

0.5 litres contain 1.1 moles
therefore 1 litre will have= 1*1.1/0.5
molarity=2.2M

Answer 2

The correct answer is 2.2 mol/L

Step-by-step explanation:

Molarity of a solution is used to determine the concentration of that solution. It is mathematically expressed as

Molarity (M) = number of moles ÷ volume (in liters or dm³)

The unit for molarity is mol/L or mol/dm³ or M

From the question, number of moles is 1.1 moles and the volume is 0.5 liters.

Hence,

Molarity = 1.1 ÷ 0.5

Molarity = 2.2 mol/L
