[tex]find \: the \: equation \: of \: variation \: first \\ \\ v = volume \: of \: gas \\ p = pressure \\ \\ therefor - \\ \\ v = \frac{k}{p} \\ \\ find \: k \: first \\ v = \frac{k}{p} \\ 42 = \frac{k}{18} \\ \\ k = 756 \\ \\ \\ \: find \: v \: or \: the \: volume \: \\ \\ v = \frac{k}{p} \\ \\ v = \frac{756}{70} \\ \\ v = 10.8 \\ \\ \\ hope \: i \: helped \: you[/tex]
