Answer:
70.128 g
Explanation:
We are given;
- Moles of sodium chloride as 1.2 mole
Required to calculate the mass of sodium chloride.
- We know that to get the number of moles of compound we divide the mass by the molar mass.
- That is, Moles = Mass ÷ Molar mass
Molar mass of NaCl = 58.44 g/mol
Therefore;
Mass of NaCl = Moles of NaCl × molar mass
= 1.2 moles × 58.44 g/mol
= 70.128 g
Hence, the mass of NaCl is 70.128 g
