write a balanced equation
convert g of water to moles, convert T to Kelvin
use stoichiometry to calculate number of moles of hydrogen formed
use combined gas law or ideal gas law to solve for V

Explanation:

#2H_2O rarr2H_2 + O_2#

#(10 g H_2O)/(18.01(g/(mol)) )= 0.556mol#

Since water and hydrogen have a 1:1 molar ratio
0.556 mol of #H_2# will be formed
#PV = nRT#

#V= nRT/P#

#V= (0.556mol)(0.082057L*atm//K*mol)(305K)//0.940atm#
#V= 14.8L#
