Question

36.2 OF LITHIUM CARBONATE TO MOLECULES

Answer 1

2.95 x 102₃

Procedure

1. The first step is to search for the formula of lithium carbonate or deduct it using nomenclature rules,

-The formula is Li₂CO₃

2. Then determine the molecular weight of the molecule

-The molecular weight is 73.891 g/mol

3. Convert from grams to moles and from moles to molecules

`36.2\text{ g Li}_2\text{CO}_3\frac{1\text{ mol}}{73.891\text{ g}}\frac{6.022*10^(23)}{1\text{ mole}}=2.95*10^{23\text{ }}molecules`
