The ideal gas law

Tutorial 1

        

The volume of a sample of sulfur dioxide at $ 20\;^oC $ and $ 1000\;mmHg $ is $ 0.525\;m^3 $. What would be the volume of this sample under standard conditions (ntp: $0\;^oC; 1\;atm$ )? Solution (Click): Conversion to Kelvin: ..........$T_1=$ $\color{red}273.15\; K$
$T_2=$ $\color{red}293.15\; K$ The ideal gas law: ..........$\frac{P_1\cdot V_1 }{T_1}=\frac{P_2\cdot V_2 }{T_2}$ Calculation: ..........$V_1=\frac{T_1\cdot V_2\cdot P_2}{T_2\cdot P_1}$ = $\frac{273.15 \cdot 0.525\cdot 1000}{293.15 \cdot 760} = 0.644\;m^3$
