Question

Answer 1

Answer #1

25.

100% pure means 100mg in 100ml of the solution

so for the preparation of 200ml of 3 % cresol we need 6g of cresol which will be obtained from 6ml of 100% Cresol

the answer will be 6ml

26.

for 2 liters of 6% glucose

2 liter = 2000ml

6% = 6mg in 100ml

6* 20 ( 2000/100=20) = 120mg

so this can be obtained from 120ml of 100% glucose

the answer will be 120ml
