How many grams in 5 moles of NaCL?

292.5 g

Explanation:

We know the formula:

No of moles = Mass ÷ Mr of the Compound

We need to find the mass, so make Mass as the subject of the formula.

Mass = No. of moles × Mr of the Compound

We know the no. of moles, as per given in question which is 5 moles.

Find the Mr of NaCl

Mass of Na = 23

Mass of Cl =35.5

Mr of NaCl = 23 + 35.5 = 58.5

Fill in the values in the formula.

Mass = 5 moles × 58.5

Mass = 292.5 g
