Answer 1

Volume of oxygen produced = 403 L

Step-by-step explanation:

Given data:

Number of moles of NaClO₃ = 12.0 mol

Volume of oxygen produced = ?

Temperature = 273 K

Pressure = 1 atm

Solution:

Chemical equation:

2NaClO₃ → 2NaCl + 3O₂

Now we will compare the moles of oxygen and NaClO₃ .

NaClO₃ : O₂

2 ; 3

12.0 : 3/2×12.0 = 18.0 mol

Volume of oxygen produced:

PV = nRT

R = general gas constant = 0.0821 atm.L/mol.K

1 atm × V = 18.0 mol × 0.0821 atm.L/mol.K × 273 K

V = 403 L .atm / 1 atm

V = 403 L
