What is the mole fraction of a solution that contains 200 g of magnesium hydroxide in 225 g of water
0.215
Explanation:
Given parameters:
Mass of magnesium hydroxide = 200g
Mass of water = 225g
Unknown:
Mole fraction of solution = ?
Solution:
The mole fraction is a measurement of concentration that expresses the number of moles of solute to that of solution.
Mole fraction =
A solution is made up of solute and solvent
Number of moles =
Molar mass of Mg(OH)₂ = 24.3 + 2(16 + 1) = 58.3g/mol
Molar mass of H₂O = 2(1) + 16 = 18g/mol
Number of moles of Mg(OH)₂ =
= 3.43moles solute
Number of moles of H₂O =
= 12.5moles solvent
Mole fraction =
= 0.215
