The balanced chemical reaction is given as:
Now, convert into litres.
So,
Density is equal to the ratio of mass to the volume.
where, M = mass and V= volume
Substitute the value of density and volume in formula to get the value of mass.
Now, number of moles of gas=
=
According to the reaction, 2 moles of sodium azide gives 3 moles of nitrogen gas.
Now, in 24.00 moles of nitrogen gas produced from= of nitrogen gas, moles of sodium azide.
number of moles of sodium azide =
Mass of sodium azide in g = .
=
=
Thus, mass of sodium azide which is required to produce of nitrogen gas =
Answer:
296 L
Explanation:
We will need a balanced equation with moles, so let's gather all the information in one place.
4Al + 3O₂ ⟶ 2Al₂O₃
n/mol: 17.4
1. Moles of O₂
2. Volume of O₂
You haven't given the conditions at which the volume is measured, so I assume it is at STP (0 °C and 1 bar).
At STP the molar volume of a gas is 22.71 L.
