Question

3. You have 4 moles of CaF2. How many grams are present?

Answer 1

1) List the quantities.

Sample: 4 mol CaF2

2) Convert moles of CaF2 to grams of CaF2.

The molar mass of CaF2 is 78.0748 g/mol.

`g\text{ }CaF_2=4\text{ }mol\text{ }CaF_2*\frac{78.0748\text{ }g\text{ }CaF_2}{1\text{ }mol\text{ }CaF_2}=312.3\text{ }g\text{ }CaF_2`

4 mol CaF2 is equal to 312.3 g CaF2.
