Molar concentration

Question

What is the concentration in mol dm3 for:

Sulphuric acid, in which 750cm3 contains 1.5 molH2SO4?

Answer 1

1 dm³ is the same a 1000 ml which is the same as 1 liter

1 cm³ is equal to 1 ml.

Molarity = moles solute/L of solution

moles = 1.5

Volume = 750 cm³ x 1L/1000 cm³ = 0.750 L = 0.750 dm³

Molarity = 1.5 moles/0.750 dm³ = 2.0 M (to 2 significant figures)
