Respuesta :
The mass, in grams, of H₂O is produced in the decomposition of ammonium nitrate is 72.06 grams.
How do we calculate mass from moles?
Mass of any substance will be calculated by using their moles as:
n = W/M, where
W = required mass
M = molar mass
Given chemical reaction is:
NH₄NO₃ → N₂O + 2H₂O
Moles of 160.1 g of NH₄NO₃ = 160.1g / 80.03g/mol = 2moles
From the stoichiometry of the reaction, it is clear that:
1 moles of NH₄NO₃ = produce 2 moles of H₂O
2 moles of NH₄NO₃ = produce 2×2=4 moles of H₂O
Mass of H₂O will be calculated as:
W = (4mol)(18.01 g/mol) = 72.04 grams (72.06 approx)
Hence, option (4) is correct.
