There is enough N2 to make 6.47 g NH3 and there is enough H2 to make 89.0 g NH3. N2 is the limiting reactant because it makes the smaller product mass. 6.47 g NH3 can be produced (this is the theoretical yield). For the following 6 questions, consider the following balanced chemical equation: 2C2H2 + 5O2 → 4CO2 + 2H2O.

Mole Calculation Practice Worksheet Answer the following questions: 1) How many moles are in 25.0 grams of water? 2) How many grams are in 4.500 moles of Li 2O? 3) How many molecules are in 23.0 moles of oxygen? 4) How many moles are in 3.4 x 10 23 molecules of H 2SO 4? 5) How many molecules are in 25.0 grams of NH 3?
There are three mole equalities. They are: 1 mol = 6.02 x 1023 particles. 1 mol = molar mass in g (periodic table) 1 mol = 22.4 L for a gas at STP. Each equality can be written as a set of two conversion factors. They are:
