If the pressure of 1.50 L of hydrogen gas at 100 °C decreases from 0.500 atm to 0.115 atm, what is the final volume? Assume temperature remains constant at 3.45 L. Chemistry Gases Molar Volume of a Gas 1 Answer anor277 Feb 25, 2017 #P_1V_1=P_2V_2#. #V_2~=6*L# Explanation: #V_2=(P_1V_1)/P_2# (and this will clearly give us an answer with units of volume as required.) #V_2=(0.500*atmxx1.50*L)/(0.115*atm)=???# Answer link Related questions How do stoichiometric ratios relate to molar volume of a gas?
