Question

how many molecules are there in 500g of calcium carbonate

Answer 1

Answer:

5 moles

Explanation:

Mass of calcium carbonate = 500g

Gram molecular mass of CaCO3 = 100g

To calculate the number of moles, apply the formula given:

Given Mass÷molar mass

Number of moles = 500/100

=5

Thus, number of moles in 500g of CaCO3 is 5

Answer 2

Answer:

there are 100.0869 are there in calcium carbonate
