250 ml of 1.5m solution of sulphuric acid is diluted by adding 5 L of water. What is the molarity of the diluted solution?


sankappashettypammh3: Does m represent Molarity or Molality?
danielochich: It represents molality

Molarity = moles / 1000 cm³

When we dilute the solution we get a total volume of :

250 ml + (5 × 1000) ml = 5250 ml

Which is 5250 cm³

1.5 moles are in 1000 cm³

How many moles are on 250 ml:

(250 / 1000) × 1.5 = 0.375 moles.

These moles are in 5250 cm³

The molarity is thus :

(1000 / 5250) × 0.375 = 0.07143 M
