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 is 14 litres.

Answer 2

Answer:

14 litres

Explanation:

given

weight of methane=10grams

Now finding molar mass of CH4

=(1×12)+(1×4)

=12+4

=16

Now finding number of moles

=10/16

=0.625

Now finding volume of methane for 10 grams

n=V/22.4

0.625=V/22.4

V=14

Therefore volume of 10 grams of methane is 14 liters
