A sample of argon has a volume of 205 mL when its temperature is -44.0 oC and its pressure is 712 mm of Hg. What would be the vo
anzhelika [568]

Answer:

231.98 mL

Explanation:

V₁ = Initial volume = 205 mL

V₂ = Final volume

P₁ = Initial pressure = 712 mmHg

P₂ = Final pressure = 750 mmhg (STP)

T₁ = Initial temperature = -44 °C = 229.15 K

T₂ = Final temperature = 273.15 K (STP)

From Combined gas law

\frac{P_1V_1}{T_1}=\frac{P_2V_2}{T_2}\\\Rightarrow V_2=\frac{P_1V_1T_2}{T_1P_2}\\\Rightarrow V_2=\frac{712\times 205\times 273.15}{229.15\times 750}=231.98\ mL

Volume of the argon at STP is 231.98 mL
