Question 2 A compound has the empirical formula OH and has a molecular weight of 34 g/mol. The true formula is:

What is the empirical formula of an compound containing 63.5% Fe; 36.5 % S?

4 NH3 + 7 O2 —-> 4 NO2 + 6 H2O   Use the following conversions: 1 mol = MW in g (2 d.p.) = 22.414 L Calculate the percent yield of water if 80.0 g of H2O (MW = 18.02 g H2O) are formed from reaction of 80.0 L of NH3 gas at STP (MW = 17.03 g NH3) and excess O2. When entering your percentage do not type the % symbol.
