Question

How many grams are in 4.80 mol of sodium chloride ( NaCl )?

Answer 1

Hello There!!

We know,

Molar Mass of Sodium= 23 and,

Molar Mass of Chlorine= 35.45

$\therefore \text{Molar Mass of Sodium chloride= 58.44 }\text{g/mol}$

So, The Molar Mass in Grams=

$58.44 \frac{\text{g}}{ \cancel\text {mol}} \times 4.80 \: \cancel\text{mol} \\ \\ \text{Mass of NaCl }= 280.51\: \text {gram}$

Hope This Helps!!

Answer 2

$w = \text{Number of mols} \times \text{Molar mass}=4.8 \times 58.5=280.8~ g$
