41 g of MgCl^2 is how many moles of magnesium chloride?
kari74 [83]

Answer:

0.43 mol.

Explanation:

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

<em>no. of moles (n) = mass/molar mass</em>

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

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