Question

Number of grams of nitrogen dioxide that are produced from 4 moles of nitric oxide

Answer 1

184 g of NO₂

Step-by-step explanation:

The balance chemical equation for the synthesis of NO₂ from NO is as follow;

2 NO + O₂ → 2 NO₂

Step 1: Calculate moles of NO₂ produced:

According to balance chemical equation,

2 mole of NO produced = 2 moles of NO₂

So,

4 moles of NO will produce = X moles of NO₂

Solving for X,

X = 2 moles × 4 moles / 2 mole

X = 4 moles of NO₂

Step 2: Calculate Mass of NO₂ as:

Moles = Mass / M.Mass

Solving for Mass,

Mass = Moles × M.Mass

Putting values,

Mass = 4 moles × 46.0 g/mol

Mass = 184 g of NO₂
