Question

Calculate the volume of 10g of methane gas​

Answer 1

Given :

• Weight of methane(CH₄) = 10 g

To find :

• Volume of  CH₄

Solution :

Here we have ;

⇒ Weight = 10g of CH₄

Now finding molar mass of CH₄ :

⇒ Molar mass = (1 * 12) + (4 * 1)

⇒ Molar mass = 12 + 4

⇒ Molar mass (M) = 16 g

Now finding number of moIes :

⇒ Number of moIes (n) = 10/16

⇒ Number of moIes (n) = 0.625

Now finding voIume of 10g of CH₄ :

⇒ n = V/22.4

⇒ 0.625 = V/22.4

⇒ V = 0.625 * 22.4

⇒ V = 14 litres.

Therefore,

Volume of 10g of methane gas​  = 14 litres.
