Chapter 1, Problem 9Q

To determine

To explain: The exact measurement of the other ingredients.

Answer to Problem 9Q

The other ingredients should be measured within the variation by 10%.

Explanation of Solution

Introduction:

There is always a slight possibility of uncertainty in any measurement. So, the measurements can never be exact. So, the correct number of significant figures of a certain quantity must be written in order to reduce the uncertainty.

According to the given statement, all the measured ingredients must be exact. If the variation for eggs is 10% then the other ingredients must be measured in between the variation of 10% only. So, the other ingredients must be measured as same variation as the eggs.

Conclusion:

Hence, the other ingredients should be measured within the variation by 10%.
