Answer:
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
