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

$\frac{V_{1}}{T_{1}} = \frac{V_{2}}{T_{2}}$ $V_1/T_1=V_2/T_2$ ; $V_{2} = \frac{V_{1}}{T_{1}} \times T_{2}$ $V_2=V_1/T_1xxT_2$

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

Volume slightly reduces as anticipated.

Standard temperature is assumed to be laboratory temperature.
