Answer : The mass of combustion products formed are 134 lbs.
Explanation :
The balanced chemical reaction will be:
Given :
Mass of = 29 lbs = 13154.2 g
conversion used : 1 lbs = 453.592 g
Molar mass of = 44 g/mole
First we have to calculate the moles of .
Now we have to calculate the moles of and
.
From the balanced chemical reaction we conclude that,
As, 1 mole of react to give 3 moles of
So, 298.9 mole of react to give
moles of
and,
As, 1 mole of react to give 4 moles of
So, 298.9 mole of react to give
moles of
Now we have to calculate the mass of and
.
Molar mass of = 44 g/mole
Molar mass of = 18 g/mole
and,
The total mass of products = Mass of + Mass of
The total mass of products = 86.98 + 47.44 = 134.42 ≈ 134 lbs
Therefore, the mass of combustion products formed are 134 lbs.
