Moles of CH₄ = 6.3

Further explanation

Given

3.8 x 10²⁴ molecules of CH₄ gas

Required

The number of moles

Solution

1 mol = 6.02 x 10²³ particles (molecules, atoms, ions)

Can be formulated :

N = n x No

No = Avogadro's number

Input the value :

n = N / No

n = 3.8 x 10²⁴ /6.02 x 10²³

n = 6.3 moles

There are 6.312 moles of CH4 gas in 3.8 x 10²⁴ molecules.

HOW TO CALCULATE NUMBER OF MOLES:

  • The number of moles of methane gas can be calculated by dividing the number of molecules contained in the gas by Avogadro's number.

  • no. of moles = no. of molecules ÷ 6.02 × 10²³

  • According to this question, 3.8 x 10²⁴ molecules were given. The number of moles is calculated as follows:

  • no. of moles = 3.8 × 10²⁴ ÷ 6.02 × 10²³

  • no. of moles = 0.6312 × 10¹

  • no. of moles = 6.312moles.

Therefore, there are 6.312 moles of CH4 gas in 3.8 x 10²⁴ molecules.
