Question 1

What is the molarity of a solution containing 1.2 grams of solute in 450 mL of solution? (

molar mass of solute = 24 g)

= 0.1 M

Explanation:

450mL = 0.45L

If 24g of a solute are weighed by 1 mole of solute

1.2g of a solute will be weighed by (1.2 : 24)

= 0.05 moles of a solute.

0.45L of a solution are occupied by 0.05 moles

1L will be occupied by (1:0.45) * 0.05

= 0.1 M
