Question

An aqueous solution of glucose is 20 % in strength. The volume in which 1 g - mole of it is dissolved will be : (A)  9 L  (B)  1.8 L  (C)  8 L  (D)  0.9 L

∵ 20 g glucose is dissolved in 100 mL solution â´ 1 g glucose is dissolved in = (100/20) 180 g ( g-mole) glucose is dissolved in = (100 Ã 180/20) = 900 mL = 0 .9 L

Q. An aqueous solution of glucose is $20%$ in strength. The volume in which $1 g$ - mole of it is dissolved will be :

$9 L$

$1.8 L$

$8 L$

$0.9 L$

$∵ 20 g$ glucose is dissolved in $100 m L$ solution
$∴ 1 g$ glucose is dissolved in $= \frac{100}{20}$
$180 g$ ( $g$ -mole) glucose is dissolved in
$= \frac{100 \times 180}{20} = 900 m L = 0.9 L$

Q. An aqueous solution of glucose is 20% in strength. The volume in which 1g - mole of it is dissolved will be :

9L

1.8L

8L

0.9L
