Question

Equal weights of ethane and hydrogen are mixed in an empty container, then find the Mole fraction of ethane in the mixture.
Answer with Explanation. ​

Answer 1

Answer:

i think it can help u if it kepp this as brainlist answer

Explanation:

Let x g each of hydrogen and ethane are mixed.

The moles of hydrogen and methane are

x\2

and

x\30

respectively.

The mole fraction of hydrogen is

=x2\x\2+x\30=15\16

The partial pressure of hydrogen is the product of its mole fraction and total pressure.

Thus

Partial pressure of H2 Total pressure=mole fraction of hydrogen=15\16
