Question

A LPG Cylinder contains 16 kg of
methane (CH) gas. How many moles of
methane gas does the cylinder contain?
​

Answer 1

Explanation:

Moles = 16×10^3÷14

Answer 2

Answer:

Explanation:

Atomic mass of carbon+atomic mass of hydrogen....

Atomic mass of carbon=6+6

Atomic mass of hydrogen=1+1

Molar mass of methane=6+6+2(4)

=20u

Given mass of methane=16kg=16000g

Formula

No. of moles=given mass /molar mass

No of moles=16000g/20u

=0.00125mol
