4NH3 + 5O2 4NO +6H2O
3.25 g of NH3 are allowed to react with 3.50 g of O2. How many grams of NO are formed?
We know from this reaction that 4 moles of ammonia react with 5 moles of Oxygen gas to Form 4 moles of Nitrogen oxide and water.
So we have to make the convention from grams to moles, for that you have to get your periodic table and calculate the masses of each compound.
NH3 has a molar mass of 17.0 g/mol
So ask yourself: if 17.0g is equal to 1 mol, 3.25 g is equal to how many moles?
Once you've covered the mole conversion think what's the limiting reactant
The molar mass of Oxygen gas is 16.0 g/ mol.
So from the calculated moles follow the stoichiometry and think that you will have x given moles of Nitrogen oxide depending on which one is your limiting reactant
