Question

Average serving size is 500mls which is 1050kj.

What is the total number of kJs of energy in a 1.25 litre bottle of Lemon Squash?

Answer 1

2625 kJ

Explanation:

We assume the energy is proportional to the volume:

energy/volume = 1050 kJ/(500 mL) = E/(1250 mL)

Multiply by 1250 mL:

E = (1250/500)(1050 kJ) = 2625 kJ

The number of kJ in 1.25 L of Lemon Squash is 2625 kJ.
