1) A 10 ppt solution is equivalent to which of the following
a)1 gram / liter
b) 0.1 grams / 100 ml
c) 10 grams / liter
d) 10 grams / 100 ml
Homework Answers
ANSWER : B and C
We have, ppt = (mass of solute / mass of solution ) 
1000
A) 1 gm / L
Assume density of solution = 1 g / ml , then mass of 1 L solution = 1000 g
Therefore, (1 g / 1000 g ) 1000 = 1 ppt
B) 0.1 g / 100 ml.
Assume density of solution = 1 g / ml , then mass of 100 solution = 100 g
Therefore, (1 g / 100 g ) 1000 = 10
ppt
C) 10 g per litre
Assume density of solution = 1 g / ml , then mass of 1 L solution = 1000 g
Therefore, (10 g /1000 g ) 1000 = 10
ppt
D) 10 g per 100 ml
Assume density of solution = 1 g / ml , then mass of 100 solution = 100 g
Therefore, (10 g / 100 g ) 1000 = 100
