Answer:
1 space molal space solution space contains space 1 space mole space of space solute space in space 1 space Kg space of space straight H subscript 2 straight O
Number space of space moles space of space solute equals space 1 space

Number space of space moles space of space space straight H subscript 2 straight O space equals space fraction numerator Wt space of space space straight H subscript 2 straight O over denominator Mol space wt space of space space straight H subscript 2 straight O end fraction
space space space space space space space
space space space space space space space space space space space space space space space space space space space space space space space space space space space space space space space space space space space space space space space space space space space space equals 1000 over 18

space space space space space space space space space space space space space space space space space space space space space space space space space space space space space space space space space space space space space space space space space space space space equals 55.55 space moles space of space space straight H subscript 2 straight O

Mole space fraction space of space solute space equals fraction numerator No. space of space moles space of space solute over denominator No. space of space moles space of space solute space plus space No. space of space moles space of space solvent end fraction

space space space space space space space space space space space space space space space space space space space space space space space space space space space space space space space space space space space space space space space equals fraction numerator 1 over denominator 1 plus 55.55 end fraction

space space space space space space space space space space space space space space space space space space space space space space space space space space space space space space space space space space space space space space space equals 0.01768
