Question

State the mole fraction of glucose in 10% w / w glucose solution.​

Answer 1

Explanation:

What is the mole fraction of glucose in 10%w/w glucose solution? A. 0.01.

Answer 2

ANSWER: Mole fraction of glucose=0.01

EXPLANATION:

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