i>Chapter 10, Problem 27QAP, Covert the following numbers of kilojoules into kilocalories. (Remember: kilo means 1000.) 652.1 kJ kJ

Interpretation Introduction

(a)

Interpretation:

Convert 652.1 kilojoules to kilocalories.

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.

Explanation

The given conversion is: conversion of kilojoules to kilocalories.

1 kilojoule is equal to 0.239006 kilocalorie.

1 kJ = 0.239006 kcal

Thus, conversion factor is given by:

1 kJ0.239006 kcal

So,

652
