C. 54.9 J
5.49 X 10 to the power of 4

Answer 1

9.62 × 10² J

Step-by-step explanation:

In this problem, we need to convert 230 calories to joules. For this, we must know the conversion from calories to joules.

1 Calorie = 4.184 Joules

To find Joules in 230 calories, multiply 4.184 by 23. So,

230 Calorie = (230 × 4.184) Joules

= 962.32 Joules

or

230 Calories = 9.62 × 10² J

So, the correct option is (A).
