What is the volume of 1.2 moles of water vapor at stp? spell check round final answers to the tenth position, one place after the decimal. only report the numerical answer.

At S.T.P  the  molar volume of a gas  is  22.4L,that  is 1mol=22.4l therefore  the  voume  of  1.2 moles  of water   vapor is
1.2 x22.4=26.7L

   alternatively
from  ideal gas  law v=nRT /P
At  S.T.P the  temperature  is 273k  and pressure is  1atm
R=0.0831 atm/mol/k
v=(1.2  x 0.0821 x273)/(1am)=26.8L
