Question

Calculate the molarity of the following solution.
45.7 g C10H12 in 5230 mL of solution
unit:

Answer 1

Answer:

Molarity = Moles of solute/Volume of solution(in Litres)

Solute = C10H12

moles of solute = Mass/Molar Mass

Molar Mass of C10H12 = 10(12) + 12(1)

= 132gmol-¹

Mole = 45.7/132 = 0.346mol

Molarity = 0.346/5.23

=0.066M
