ANSWER: Mole fraction of glucose=0.01

EXPLANATION:

10percentage \:  \frac{w}{w}  \: means \\ 10g \: solute \: in \: 100g \: solution \\ moles \: of \: glucose =  \frac{10}{180} =  \frac{1}{18} = 0.055 \\ moles \: of \: water =  \frac{90}{18}  = 5 \\ mole \: fraction \: of \: glucose =  \frac{0.055}{5 + 0.055}   \\  \:  \:  \:  \:  \:  \:  \:  \:  \:  \:  \:  \:  \:  \:  \:  \:  \:  \:  \:  \:  \:  \:  \:  \:  \:  \:  \:  \:  \:  \:  \:  \:  \:  \:  \:  \:  \:  \:  \:  \:  \:  \:  \:  \:  \:  \:  \:  \:  \:  \:  \:  \:  \:  = 0.01088</p><p>
