Question

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

Answer 1

We use old `"Charles' Law"`; `VpropT`; 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_1xxT_2`

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

Volume slightly reduces as anticipated.

Standard temperature is assumed to be laboratory temperature.
