any help would be appreciated

Remember that you are assessed on your explanations to the problem and therefore need to estion. A correct answer without an explanation will not earn any credit. The volume V of an ideal gas varies directly with the temperature T' and inversely with the pressure P. A cylinder contains oxygen at a temperature of 310 degrees K and a pressure of 18 atmospheres in a volume of 120 liters. Find the pressure if the volume is decreased to 100 liters and the temperature is increased to 340 degrees K. Round your answer to two decimal places. The pressure is Number atmospheres
