A mixture was found to contain 1.05g of sio2, 0.69g of cellulose, and 1.82g of calcium carbonate, what percentage of calcium carbonate is in the mixture

Mass percentage is another way of expressing concentration of a substance in a mixture. Mass percentage is calculated as the mass of a component divided by the total mass of the mixture, multiplied by 100%. It is calculated as follows:

% CaCO3 = (1.82g of calcium carbonate / (1.05 g SiO2 + 0.69 g of cellulose + 1.82g of calcium carbonate)) x 100% = 51.12% Calcium carbonate
