# A 153.5 mL volume of gas is measured at 71.1"^oC. If the pressure remains unchanged, what is the volume of the gas at standard temperature?

Nov 22, 2016

We use old $\text{Charles' Law}$; $V \propto T$; where pressure is CONSTANT, and temperature is quoted on the Absolute Scale.

#### Explanation:

${V}_{1} / {T}_{1} = {V}_{2} / {T}_{2}$; ${V}_{2} = {V}_{1} / {T}_{1} \times {T}_{2}$

=(153*mL)/(344.3*cancelK)xx298.15*cancelK=??*mL

Volume slightly reduces as anticipated.

Standard temperature is assumed to be laboratory temperature.
