Chapter 17: Q.9.97 (page 584)

How many liters of $12 % (m / v)$ $KOH$ solution would you need to obtain $75 g$ of glucose?

Short Answer

Expert verified

The volume of the solution is $0.716 L$ .

Step by step solution

Given information

The percentage of KOH solution is given which is $12 %$ .

Explanation

Molarity is defined as the ratio of concentration over volume.

The percentage of KOH solution is given which is $12 %$ $(w / v)$ , it means that $12 gm$ of $KOH$ is present in $100 mL$ of water.

Therefore, for 86 g of KOH, the volume will be

$\frac{86 gm}{12 gm} \times 100 = 7.166 \times 100 = 716.66 mL$

The unit conversion for mL into L is given as follows:

$716.66 mL \times \frac{1 L}{1000 mL} = 0.716 L$

Thus, the volume of the solution is $0.716 L$ .
