Question

a) define solution, solute and solvent
b) calculate the mole fraction of H2so4 in a solution containing 98% H2so4 by mass​

Answer 1

Answer:

A solution is a homogeneous mixture of one or more solutes dissolved in a solvent. solvent: the substance in which a solute dissolves to produce a homogeneous mixture. solute: the substance that dissolves in a solvent to produce a homogeneous mixture.

Explanation:

Weight of H2SO 4=98g

Molecular weight of H2SO4=98g

No. of moles of H] [2SO4=

Molecular weight/Given weight = 98/98=1 mole

Weight of water =2g

Molecular weight of water =18g

No. of moles of water = 18/2 = 9/1mol

Mole fraction of H2SO4 = 1/+1 /9/1 =9/10

=0.9
