Question

Explain how you would determine the molar mass of C2H6.

Answer 1

Answer:-

Name of Chemical Compound: (if given otherwise not necessary) Ethane.

Chemical formula: C2H6.

Finding molar mass of Ethane(C2H6):-

Molar mass of Ethane = 12×2+1×6

Molar mass of Ethane = 2 + 6

Molar mass of Ethane = 30 g/mol

[ Note:

• Molar mass: Mass(is represented/taken in grams)of one mole of a substance.

• g/mol means grams per mole ].

Answer 2

Molar mass of ethane is determined by adding atomic mass of all the constituent atoms.

Step-by-step explanation:

Molar mass of a molecule is determined by adding all the atomic masses of constituent atoms.

In ethane molecule, there are two carbon atoms and six hydrogen atoms.

Atomic mass of carbon is 12g and atomic mass of hydrogen is 1g.

So molar mass of ethane is-
`(2* atomic mass of C)+(6* atomic mass of H)` or
`(2* 12g)+(6* 1g)` or 30g.
