According to the law of ideal gases, when the temperature of a gas stored inside an expandable chamber is kept constant, the volume of gas is inversely proportional to the amount of pressure that the gas exerts on the chamber’s surface. Volume is a function pressure. If P represents the amount of pressure exerted and V ( P ) represents the volume of gas at P , then V ( P ) = k P . When V ( P ) is measured in liters (L) and P is measured in atmospheres (atm), the units of k , a constant based on the identity of the gas, are liters per atmosphere (L/atm). If k = 8.00 , what is the instantaneous rate of change of the chamber’s volume with respect to pressure, V ′ ( P ) or d V d P , when the gas exerts 2.10 atm of pressure on the chamber’s surface? Round your answer to the nearest tenth of a liter per atmosphere. V ′ ( 2.10 ) = L/atm
