Amixture 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?

51.1 % of the mixture is calcium carbonate

Explanation:

Step 1: Data given

A mixture contains 1.05 grams of SiO2, 0.69 grams of cellulose and 1.82 grams of CaCO3

Step 2: Calculate the total mass of the mixture

Total mass = mass of SiO2 + mass of cellulose + mass of CaCO3

Total mass = 1.05 grams + 0.69 grams + 1.82 grams

Total mass = 3.56 grams

Step 3: Calculate percentage of calcium carbonate is in the mixture

% caCO3 = (mass CaCO3 / mass of mixture) *100%

% CaCO3 = (1.82 grams / 3.56 grams ) * 100%

% CaCO3= 51.1 %

51.1 % of the mixture is calcium carbonate

i think that is the right

hurricanes form when warm, moist air from the ocean surface quickly rises into the atmosphere and forms storm clouds and rain. when the clouds are formed, heat is released which warms the cool air in the upper regions of the atmosphere so that the cycle can continue. which two phases of the water cycle are repeated in this process?
