Answer:
Explanation:
D
Answer:
The answer to your question is 68 g
Explanation:
Data
mass of H₂ = 12 g
mass of NH₃ = ?
Balanced chemical reaction
3H₂ + N₂ ⇒ 2NH₃
Process
1.- Calculate the molar mass of H₂
H₂ = 1 x 6 = 6
NH₃ = 2[(14 x 1) + (3 x 1)]
= 2[14 + 3]
= 2[17]
= 34 g
2.- Use proportions to find the mass of NH₃
6 g of H₂ --------------- 34 g of NH₃
12g of H₂ ---------------- x
x = (12 x 34) / 6
x = 408/6
x = 68 g of NH₃
The balanced equation is C6H14(g) + 19/2O2(g) → 6CO2(g) + 7H2O(g). If you are given 7.9 moles C6H14, multiply it by a ratio of 19/2/1 to get the moles of oxygen. Then, you will get 75.05 moles of O2.
