Question

What is the mole fraction of glucose in 10 % w/W glucose solution? (A) 0.01 (B) 0.02 (C) 0.03 (D) 0.04

Tardigrade Admin · Accepted Answer

No. of moles of glucose = (10/180) = 0.0555 mol No. of moles of water = (90/18) = 5 mol Number of moles of solution = 5.0555 mol Mole fraction of glucose =( textNo. of moles of glucose/ textNo. of moles of solution) = (0.0555/5.0555) = 0.01

Q. What is the mole fraction of glucose in $10% w / W$ glucose solution?

$0.01$

$0.02$

$0.03$

$0.04$

No. of moles of glucose $= \frac{10}{180} = 0.0555 m o l$
No. of moles of water $= \frac{90}{18} = 5 m o l$
Number of moles of solution $= 5.0555 m o l$
Mole fraction of glucose $= \frac{No. of moles of glucose}{No. of moles of solution}$
$= \frac{0.0555}{5.0555} = 0.01$
