Answer:- 71.7 calories

Solution:- it is a unit conversion problem where we need to convert joules into calories.

The unit conversion for these energy units is:

1 calorie = 4.184 joule

The given energy is 300 joules and has to be converted to calories. We will show the set up using dimensional analysis.

[tex]300joules(\frac{1calorie}{4.184joules})[/tex]

= 71.7 calories

So, the energy in calories is 71.7.
