Answer 1

Step : Express in Standard Form

The given number is,

$60,230,000,000,000,000,000,000$

This value can be expressed in the standard form as,

$6.023\times {10}^{22}$

Hence the given statement can be rewritten as,

$6.023\times {10}^{22}$molecules are contained in a drop of water weighing $1.8gm$.
