Question
from the balanced equation 4NH3 +7O2 - 4NO2 + 6H2O.
How many grams of oxygen are necessary to produce 4.50 moles of NO2?
I think its 11 grams or 22 grams but im not sure. please help!!
First the number of moles of O2,
molesO2= (4/7) moles NO2
Notice those came from the balanced equation.
Put in 4.5 moles NO2, and you have moles of O2.
Grams of O2? multiply moles of O2 by 32.
what do you mean I don't understand any of what you said execpt for Grams of O2? multiply moles of O2 by 32. sorry

Answers
Grams of O2 = moles of O2 x molar mass of O2
Molar mass of O2 = 32 g/mol
Therefore, 4.50 moles of NO2 requires 11 grams of O2.
Molar mass of O2 = 32 g/mol
Therefore, 4.50 moles of NO2 requires 11 grams of O2.
