Question

Convert `12.044 xx 10^(22)` molecules of sulphur dioxide into moles.

Answer 1

We know that :
`6.022 xx 10^(23)` molecules of sulphur dioxide ` = 1` mole
So, `12.044 xx 10^(22)` molecules of sulphur dioxide `= (1)/(6.022 xx 10^(23)) xx 12.044 xx 10^(22)`
`= 2/10`
`0.2` mole
Thus, `12.044 xx 10^(23)` molecules of sulphur dioxide are `0.2` mole.
