Answer 1

Answer : This is equal to 648.954 joules

Solution :

As we are given that 12 ounce can of coke contains 155 calories. Now we have to calculate in joules.

Conversion factor used : 1 calorie = 4.1868 joules

As, 1 calorie is equal to 4.1868 joules

So, 155 calories is equal to
`(155cal)/(1cal)* 4.1868J=648.954Joules`

Therefore, the 155 calories is equal to 648.954 joules

Answer 2

Answer:
`648.954J`

If we want to know how many Joules contains a 12-ounce can of coke, we have to transform the calories
`cal` to Joules
`J`.

Knowing that
`1cal=4.1868J` we can make the transformation as follows:

`155cal (4.1868J)/(1cal)=648.954J`

Therefore, at 12 ounce can of coke contains 648.954 Joules
