Chapter 2: Problem 18

Without using a calculator, a) Which weighs more, 18 elephants or two dozen elephants? b) Which weighs more, \(5.136 \times 10^{23}\) sodium atoms or one mole of sodium atoms?

Short Answer

Expert verified
a) Two dozen elephants weigh more. b) One mole of sodium atoms weigh more.

Step by step solution

01

Comparing the number of elephants

A dozen is equal to 12. Therefore, two dozens equal to 24. Compare the number 18 (the first given number of elephants) with 24 (the second given number of elephants). It can be observed that 24 is greater than 18.
02

Comparing the number of sodium atoms

One mole of any substance contains \(6.02214076 × 10^{23}\) particles. Comparing this with \(5.136 × 10^{23}\) sodium atoms, one can observe that \(6.02214076 × 10^{23}\) is greater than \(5.136 × 10^{23}\).
