Can someone please help me figure out the following exampleproblems? 1) A sample of nitrogen at 20.0 °C has a volume of 1,027mL at a pressure of 1,184 mmHg. To change the volume to 1,962 mL,what must be the new pressure?
2) What would be the volume of a balloon filled with 4.77 L ofH2 gas collected at 1,553 mmHg if the pressure wereincreased to 2,131 mmHg?

3) If we want to compress a gas to one-half of its original volumewithout changing the temperature, we will need to _______ thepressure

Explanation / Answer

1- 1962-1027=935ml=0.935l
2) (P1V1) = (P2V2) (1184)(1o27)=(1982)(p2) P=1215968/1962=619.76mmhg 2--(P1V1) = (P2V2) (4.77)(1553)=(2131)(v2) v=7407.81/2131=3.48L 3) increase
