Question

41 g of MgCl^2 is how many moles of magnesium chloride?

Answer 1

0.43 mol.

Step-by-step explanation:

• Knowing that the no. of moles can be calculated using the relation:

no. of moles (n) = mass/molar mass

mass of MgCl₂ = 41.0 g & molar mass of MgCl₂ = 95.211 g/mol.

∴ n = mass/molar mass = (41.0 g)/(95.211 g/mol) = 0.43 mol.
