Question

Ammonium nitrate can decompose explosively when heated according to the following equation:
2NH4NO3(s) → 2N2(g)+4H2O(g)+O2(g)
How many liters of gas would be formed at 505 ∘C and 1.00 atm pressure from an explosion of 445 g of NH4NO3?

Answer 1

Answer:

354.7 liters of gas are been formed.

Explanation:

A typical problem to apply the Ideal Gases Law.

P.V = n.R.T

Pressure : 1 atm

Volume: Unknown

Mol: 445g/molar weight NH4NO3

R = 0.082 L.atm/mol.K

T°K  = 505°C + 273 =778K

445g/80.04 g/m = 5.56 mol

1 atm . V = 5.56mol . 0.082 L.atm/mol.K . 778K

V= (5.56mol . 0.082 L.atm/mol.K . 778K) /1atm

V= 354,7 L
