Question

A can of soft drink 335mL provides 130 calories. A bottle of mixed berry juice 295mL provides 630kJ. which provides the greater total energy? which provides the greater energy per milliter ?

Answer 1

First change the unit of energy from kj to calories as follows:

   1.00 kJ = 0.23900573614 calories

So, 630 KJ * 0.23900573614 calories / 1.00 KJ

= 150.6 calories

According to the problem; A can of soft drink 335mL provides 130 calories. A bottle of mixed berry juice 295mL provides 630kJ or 150.6 calories

Thus the greater energy provide by bottle of mixed berry juice.

Now calculate the amount of energy per milliliter as follows:

For soft drink;

335mL soft drink provide = 130 calories

So, 1 ml soft drink provides = 130 calories / 335 ml*1 ml

= 0.388 calories.

And

295mL of mixed berry juice provide = 150.6 calories

Then

1 ml mixed berry juice provides = 150.6 calories / 295 ml*1 ml

= 0.511 calories.

Hence mixed berry juice provides the greater energy per milliter
