* How many grams of glucose are in 185ml of 5.50% (m/v) glucose solution
→If 5.50 gram of glucose = 100 ml solution
So , 185ml glucose solution contain :
185 ml× 5.50 = 10.18 gram of glucose
The grams of glucose in 185 ml of 5.50% glucose solution is m = 10.18 grams
* Solution that is 18.5% (v/v) methyl-alcohol , if bottle contain 1.99L solution , what is the volume in millilitres of methyl alcohol
→1st convert L of solution into ml , 1.99L =1990ml
if 18.5 ml methyl alcohol= 100 ml solution
So , 1990ml solution contain :
1990 × 18.5 = 368.15 ml of methyl alcohol
Volume in millilitres of methyl alcohol is
v= 368.15 ml
