Question

How to solve this without a calculator $4.6 \times 10^{24} / 6.022 \times 10^{23} =$

Open in App

Solution

$\frac{4.6 \times 10^{24}}{6.022 \times 10^{23}} = \frac{4.6}{6.022} \times \frac{10^{24}}{10^{23}} = \frac{4.6}{6.022} \times 10 = \frac{46}{6022} = 6.022 \times 7 = 42.154 6.022 \times 8 = 48.176$
$\Rightarrow$ 46 lies between 42.154 and 48.176
Thus, $\frac{4.6}{6.022}$ can be appxomiated to 7.5.
