A sample of nitrogen occupies 11.2 liters under a pressure of 580 torr at 32◦C. What volume would it occupy at 32◦C if the pressure were increased to 810 torr?
pV=nRT.n=pV/RT = 77.327 x 11.2/8.314 x 305 = 0,34153823 moles.V=nRT/p= 0,34153823 x 8.314 x 305/107.991 = 8,01976457 L.

A sample of nitrogen gas occupies a volume of 2.50 L at 25 <sup>0 </sup>C. If the pressure is held is held constant, what volume does the gas occupy?
V1/T1 = V2/T22.5/298 = V2/368V2 = 2.5×368/298 V2 = 3.087L

A sample of oxygen occupies 47.2 litres under a pressure of 1240 torr at 25<sup>o</sup>C. What volume would it occupy at 25<sup>o</sup>C if the pressure were decreased to 730 torr?
In this question, temperature, T does not change (is constant) hence only pressure, P and volume, V changes.In that case we apply Boyle's Law, P1V1=P2V2P1=1240 torrentP2=730 torrentV1=47.2 LV2 = P1V1/P2...
