Question

3.00 moles of gas are pumped into a 1.00L rigid container with a pressure of 1.98 atm. The gas is released from the container until the pressure is 0.78 atm, how many moles of gas remain in the container?​

Answer 1

Answer:

1.18 moles of gas

Explanation:

3.00 moles of gas are pumped into a 1.00L rigid container with a pressure of 1.98 atm. The gas is released from the container until the pressure is 0.78 atm, how many moles of gas remain in the container?​

for the sealed rigid container, the pressure is directly proportional to the amount of gas

3.00moles/1.98  atm =  ? moles/0.78 atm

? = 3.00 X 0.78/1.98  =1.18 moles of gas
