Can someone help me with this?-- 15 pts! 2H2 + O2 → 2H2O

At the beginning of the reaction, it is measured that there are 15.0 g of hydrogen (H2) and 97.0 g of oxygen (O2).

What is the theoretical yield for the water that will be produced in the reaction? (M H2O = 18.0 g/mol; M CH4 = 16.0 g/mol)

2.73 x 101 g H2O
1.34 x 102 g H2O
1.08 x 102 g H2O
5.38 x 100 g H2O

1.08 x 10^2 gm of H2O

Explanation:

number of moles of O2 = 97g /32 g/moles = 3.03 moles

3.03 moles of O2 produces 6.06 moles of H2O

amount of water produced = 6.06 mol x 18 g /mol = 109.08 g = 1.08 x 10^2 g

alfred von schlieffen, german army chief of staff, was given instructions to devise a strategy that would be able to counter a joint attack. in december, 1905, he began circulating what later became known as the schlieffen plan. schlieffen argued that if war took place it was vital that france was speedily defeated.
