Answer

$n=5.47\times10^{-8} $ moles

Work Step by Step

The ideal gas law is $PV=nRT$ Since we need to find $n$, we will rearrange the above equation to make $n$ the subject of the formula: $n=\frac{PV}{RT}$ Since we know the values of $P,V,R$ and $T$, we substitute these values to find $n$: $n=\frac{100(1\times10^{-6}m^3)}{8.314(220)}$ $n=5.47\times10^{-8} $ moles
