Question

Find the number of grams

of Naf in 3. 72 X 10^22

formula units.

Answer 1

The mass of sodium fluoride was found to be 2.594 g

Formula units: n = N/Na, n = 3.72* 1022 Moles.

Na is the Avogadro number, where n is equal to 3.72*1022/6.022*1023 mol-1, or 0.0618 mol.

Molar mass, MW = 42 g/mol, is equal to n*MW = 0.0618 mol * 42 g/mol, or 2.594 g.
