Water is decomposed into hydrogen gas and oxygen gas. What mass of water must decompose to fill a 3.00 L flask to a total pressure of 2.00 atm at 298 K with a mixture of hydrogen gas and oxygen gas? 2H2O --> 2H2 (g) + O2 (g)
A. 1.47 g B. 2.95 g C. 8.84 g D. 4.42 g E. 6.63
I have a key that says its supposed to be 2.95 but I have no idea how to get there.
