Question

The molar mass of sodium chloride is 58 g/mol. how many grams of sodium chloride are in 0.5 mol of sodium chloride?

Answer 1

0.5 mols of NaCl* 58 grams of NaCl/1 mol of NaCl = 29 grams of sodium chloride

Answer 2

Answer:

$29 g. NaCl$

Explanation:

we know that it's molar mass is $58 \frac{g}{mol}$

This means that 1 mol of sodium chloride contains 58g of sodium chloride; now How many grams of $NaCl$ are in 0.5 moles?

$1 mol \longrightarrow 58g\\ 0.5 mol\longrightarrow x\\ x=\frac{0.5mol.58g}{1mol}=29g$

In 0.5 mol of NaCl there will be 29 g of sodium chloride
