Chapter 17: Q.9.97 (page 584)

How many liters of 12%(m/v)KOHsolution would you need to obtain 75gof glucose?

Short Answer

Expert verified

The volume of the solution is0.716L.

Step by step solution

01

Given information

The percentage of KOH solution is given which is12%.

02

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 12gmof KOHis present in 100mLof water.

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

86gm12gm脳100=7.166脳100=716.66mL

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

716.66mL脳1L1000mL=0.716L

Thus, the volume of the solution is0.716L.
