Question

If a 0.5 l container of juice contains 15 g of sugar, what's the concentration of sugar?

a. 30 g/l
b. 7.5 g/l
c. 3.33 g/l
d. 45 g/l

Answer 1

Concentration , g/L = mass of sugar / volume in L
Concentration , g/L = 15g / 0.5L
Concentration , g/L = 30g/L

Answer 2

we can calculate the concentration of sugar in the juice, by diving the mass of the sugar with the volume of the juice.

Concentration= mass/ volume

In this case, concentration of sugar= 15 g / 0.5 l = 30 g/L

Correct answer: A
