How many grams of water vapor (H2O) are in a 10.2 liter sample at 0.98 atmospheres and 26°C? Show all work used to solve this problem.

Use PV = nRT and solve for n. Remember that T must be in kelvin.
Then n = grams/molar mass. Solve for grams.

can someone solve this?(21.3 g Li/6.941 g Li/moleLi)*(1mole H2/1moleLi) * 22.4 L at STP * ( temp correction 297/273)* (pressure correction 1/1.4) = your answer in L of H2
