Question

hydrogen carbon contain 4.8 gram of carbon per gram of hydrogen calculate the gram atom of each​

Answer 1

Explanation:

Given:

Mass Ratio of Carbon and Hydrogen = 4.8g : 1g

Vapur Denisity (V.D): 29 ⇒ Molecular Wt. (M) = 2 x V.D = 2 x 29 = 58g

Let Wt of Carbon be 4.8K gms and Hydrogen be 1K gms.

Total Wt. 4.8K + 1K = 58gms

On Simplification K = 10

Wt of Carbon = 4.8 x 10 = 48 gms

Similarly Wt. Of Hydrogen = 10 gms

No. of Moles = Molar wt / Molcular Wt

No of Moles of Carbon = 48/12 = 4 moles

Similary No of moles of Hygrogen = 10/1 = 10 moles

Molecular Formula = C4H10

Empherical Formula = C2H5
