The limiting reagent is NO and the mass of NO₃ formed in the reaction is 1.38 grams
The limiting reactant (or limiting reagent) is the reactant that gets consumed first in a chemical reaction and they determine the amount of product formed in a reaction.
2O₃ + 3NO → 3NO₃
From the balance equation 2 moles of trioxide reacted with 3 moles of nitrogen monoxide to produce 3 moles of nitric oxide.
molarity (O₃) = 7.40 / 48 = 0.15416666666 moles
molarity(NO) = 0.670 / 30.01 = 0.02232589136 moles
Therefore,
O₃ : NO
2 : 3
Therefore, the limiting reagent is NO. It will completely be used before the reaction comes to an end.
3(30.1) g of NO produces 3(62) g of NO₃
0.670 g of NO will produce ?
cross multiply
mass of NO₃ formed = 0.670 × 186 / 90.3 = 124.62 / 90.3 = 1.38006644518 = 1.38 grams.
