Calculate the % of calcium carbonate in a mixture of calcium carbonate, sodium carbonate and magnesium sulfate if we obtained 1.73g of calcium carbonate and 2.34g of sodium carbonate and 1.93g of magnesium sulfate

Explanation:

Given parameters:

Mass of calcium carbonate = 1.73g

Mass of sodium carbonate = 2.34g

Mass of magnesium sulfate = 1.93g

Unknown:

Percentage of calcium carbonate in the mixture

Solution:

The mixture consists of :

   calcium carbonate + sodium carbonate + magnesium sulfate:

To find the percentage of calcium carbonate, we must first find the mass of the mixture by summing the masses of the different compounds that makes up the mixture:

            Mass of the mixture = 1.73 + 2.34 + 1.93 = 6.00g

Therefore,

percentage of calcium carbonate = x 100

Percentage of calcium carbonate = x 100 = 28.83%

answer: h+ its less than oh

explanation:

distance, luminosity, brightness, radius, chemical composition, and temperature
