The density of oxygen is `1.43 g L^(-1)` at STP. Determine the density of oxygen at `17^(@)C` and 800 torr.

Answer

`1.417g//L`

Explanation

`dprop (1)/(V)or(d_(1))/(d_(2))=(V_(2))/(V_(1))or d_(2)=d_(1)((V_(1))/(V_(2)))`
`"Applying combined gas law,"`
`d_(2)=(d_(1)xxT_(1)xxp_(2))/(T_(2)xxp_(1)), p_(1)="760 torr, "p_(2)="800 torr"`
`therefore" "d_(2)=(1.43xx273xx800)/(290xx760)=1.417g//L.`
