Question

A gas bottle contains 0.866 moles of gas at 688 mm Hg pressure. If the final pressure is 1.23 atm, how many moles of gas were added to the bottle

Answer 1

1.177moles

Step-by-step explanation:

convert 1.23 to mmHg

1.23 X 760 = 934.8

688mmHg = 0.866moles

934.8mmHg = x

x= 0.866 X 934.8/688

x= 1.176652326moles

x= 1.177moles
