Question

The concentration in gms per litre of a solution of cane sugar $( M = 60 )$ per litre is.

• A. 3.42
• B. 34.2
• C. 5.7
• D. 19

Answer 1

Answer: (B)

34.2

Answer 2

Isotonic solution = $\frac { w _ { 1 } } { m _ { 1 } V _ { 1 } } = \frac { w _ { 2 } } { m _ { 2 } V _ { 2 } }$

$= \frac { w _ { 1 } } { 342 \times 1 } = \frac { 6 } { 60 \times 1 } = \frac { 342 \times 6 } { 60 } = 34.2$.
