(a)
Interpretation:
Convert 75.2 kcal to joules and kilojoules.
Concept Introduction:
A conversion factor is a numerical ratio which is used to show a measurement in one unit as another unit. It is always equal to 1.

Answer to Problem 25QAP
75.2 kcal =
Explanation of Solution
The given conversion is: conversion of kilocalories to joules and kilojoules.
1 kilocalorie is equal to the 4184 joules and 4.184 kilojoules.
1 kcal = 4184 J and 1 kcal = 4.184 kJ
Thus, conversion factor is given by:
So,
(b)

75.2 cal =
Explanation of Solution
The given conversion is: conversion of calories to joules and kilojoules.
1 calorie is equal to the 4.184 joules and 0.004184 kilojoules.
1 cal = 4.184 J and 1 cal = 0.004184 kJ
Thus, conversion factor is given by:
So,
