A sample of gas has a volume of 1.40 L at a pressure of 225 mmHg. What is the new volume at a pressure of 515 mmHg?
guajiro [1.7K]

Answer:0.61L

Explanation:

P1V1/n1T1=P2V2/n2T2

n1=n2 T1=T2

Therefore;

P1V1=P2V2

225×1.4=515×V2

V2=0.61L

N.B: Increase in pressure leads to decreases in volume (Boyle's law)
