Question

Chemistry question You require 1.2 Kilograms of Calcium Carbonate per cubic metre for your growing media and you are going to supply this using limre which has 40% Calcium Carbonate how much lime do you need to add?

Answer 1

1 kg lime being 40% calcium carbonate (CaCO₃) has 0.4 kg CaCO3
1.2 kg CaCO₃/m³ x 1 kg lime/0.4 kg CaCO3 = 3 kg lime/m³ needs to be added
