Question

If 1.6 moles of an ideal gas are at a temperature of 25c and a pressure of 0.91 atm hg, what volume would the gas occupy, in liters?

Answer 1

$From\ Ideal\ Gas\ Law:\\\\PV=nRT\\\\ P-pressure\\V-volume\\n-number\ of\ moles\\R- universal\ gas\ constant\\T-absolute\ tmeperature\\\\ R=\ 8,3145J/ mol\ K\\P=0,91atm\\ n=1,6moles\\T=25c\\\\ Converting\ units:\\\\ 1atm=101,3kPa=101,3*10^3\\ 0,91atm=0,91*101,3*10^3=92,183*10^3Pa\\T=25c=273+25=298K\\\\ V=\frac{nRT}{P}=\frac{1,6*8,3145*298}{92183}=0,043m^3=43liters\\\\Answer\ is\ 43\ liters.$
