Write the no. of molecules present in 1 ...

Write the no. of molecules present in 1 millimole of `SO_(2)`.

Text Solution

Verified by Experts

1 milli mol`=10^(-3)mol`
`10^(-3)` mol of `SO_(2)=6.022xx10^(23)xx10^(-3)` molecules of `SO_(2)` ltbRgt `therefore`1 millimol of `SO_(2)=6.022xx10^(20)` molecules of `SO_(2)`.
