Answer:
The answer to your question is letter A
Explanation:
Data
Empirical formula CH₂
Molecular weight = 70 u
Process
1.- Calculate the molecular weight of the empirical formula (CH₂)
CH₂ = (12 x 1) + (1 x 2) = 12 + 2 = 14 g
2.- Divide the molecular weight by the molecular weight of the empirical formula
70/14 = 5
3.- Write the empirical formula
5(C₁H₂) = C₅H₁₀
1. C₅H₁₀
Given:
Empirical formula = CH₂
Molecular weight = 70 u
To find Molecular formula of the compound:
1.- Calculate the molecular weight of the empirical formula (CH₂)
CH₂ = [tex](12 * 1)+(1*2)=12+2=14 u[/tex]
(As molecular weight of C=12u and H= 1u)
2.- Divide the molecular weight by the molecular weight of the empirical formula
[tex]\frac{\text{Molecular weight}}{\text{ Molecular weight of Empirical formula}} = \frac{70}{14} =5[/tex]
3.- Write the empirical formula
5(C₁H₂) = C₅H₁₀
