The molecular formula =C₆H₁₂O₆
<h3>Further explanation</h3>
Given
6.00 g of a certain compound X
The molecular molar mass of 180. g/mol
CO₂=8.8 g
H₂O=3.6 g
Required
The molecular formula
Solution
mass C in CO₂ :
= 1.12/44 x 8.8
= 2.4 g
mass H in H₂O :
= 2.1/18 x 3.6
= 0.4 g
Mass O in compound :
= 6-(2.4+0.4)
= 3.2 g
Mol ratio C : H : O
= 2.4/12 : 0.4/1 : 3.2/16
= 0.2 : 0.4 : 0.2
= 1 : 2 : 1
The empirical formula : CH₂O
(CH₂O)n=180 g/mol
(12+2+16)n=180
(30)n=180
n=6
(CH₂O)₆=C₆H₁₂O₆
Answer:
For eacht 4 moles Fe consumed, we will produce 2 moles Fe2O3
The mole ration is 4:2 (option 1)
Explanation:
Step 1: The unbalanced equation
Fe + O2 → Fe2O3
Step 2: Balancing the equation
Fe + O2 → Fe2O3
On the left side we have 2x O (in O2) and on the right side we have 3x O (in Fe2O3) . To balance the amount of O on both sides, we have to multiply O2 by 3 and Fe2O3 by 2.
Fe + 3O2 → 2Fe2O3
On the left side we have 1x Fe, On the right side we have 4x (in 2Fe2O3). To balance the amount of Fe we have to multiply Fe (on the left side) by 4.
Now the equation is balanced.
4Fe + 3O2 → 2Fe2O3
For eacht 4 moles Fe consumed, we will produce 2 moles Fe2O3
The mole ration is 4:2 (option 1)
