Consider the chemical reaction:
2H2O(l)→2H2(g)+O2(g)

What mass of H2O is required to form 1.6L of O2 at a temperature of 330K and a pressure of 0.955atm ?

refer to the "ideal gas law" and to the definition of a mole

if you still need help, ask and ill can give the next hint

Find the moles of O2 needed using ideal gas law (PV = nRT)
Then use stoichiometry to find the weight of water needed.
