Answer:
Empirical Formula = C₁H₄ or CH₄
Explanation:
Data Given:
Mass of C = 12.0 g
Mass of H = 4 g
Step 1: <u>Calculate Moles of each Element;</u>
Moles of C = Mass of C ÷ At.Mass of C
Moles of C = 12.0 ÷ 12.0
Moles of C = 1.0 mol
Moles of H = Mass of H ÷ At.Mass of H
Moles of H = 4.0 ÷ 1.0
Moles of H = 4.0 mol
Moles of O = %O ÷ At.Mass of O
Moles of O = 53.924 ÷ 16.0
Moles of O = 3.370 mol
Step 2: <u>Find out mole ratio and simplify it;</u>
C H
1.0 4.0
1.0/1.0 4.0/1.0
1 4
Hence,
Empirical Formula = C₁H₄ or CH₄

Answer: 1031.33 kg of coke will produce 6400 kg of iron.
Explanation:
...(1)
...(2)
(1)+3 × (2)
...(3)
Mass of iron = 6400 kg = 6,400,000 g(1 kg = 1000 g)
Moles of iron =
According to reaction (3) , 4 moles of iron are produced from 3 moles of coke(C(s)) ,then 114,592.65 moles of iron will be produced from = moles of coke.
Mass of coke:
Hence, 1031.33 kg of coke will produce 6400 kg of iron.
