19) Hydrazine, N2H4, a substance used as rocket fuel, reacts with oxygen as follows:
N2H4 (1) + 3 O2(g) β 2 NO2(g) + 2 H20 (8)
A) If 65.0 g of hydrazine are reacted with 65.0 g of oxygen, which is the limiting reactant?
usg of Oz X Imol
.
B) How many grams of NO2 are produced from the limiting reactant in part A?
C) If 29.3 g of NO2 are obtained from the reaction in Part A, what is the percent yield?
20) What is the percent yield if 14.2 g of CO2 were produced and 17.7 g were calculated to be
produced from the reaction?

Ican determine the molar mass of an element by looking on the under the atomic mass for the element. for example the molar mass of phosphorus is 30.974 grams/mole. avogadroβs number tells me the amount of representative particles in 1 mole of any substance. this means 12.011 gram sample of carbon and a 32.0 gram sample of sulfur have the same number of atoms.
