You have 1.2 mol of sodium chloride. how many grams of this

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
