A gas mixture contains 25%he and 75% CH4 find mass% of methane?
Calculating Mass% of Methane in the Gas Mixture
To find the mass% of methane in the gas mixture, we need to consider the composition of the mixture which contains 25% helium (He) and 75% methane (CH4).

Step 1: Determine the Total Mass of the Gas Mixture
Given that the gas mixture contains 25% helium and 75% methane, we can assume the total mass of the mixture to be 100g for easy calculations.

Step 2: Calculate the Mass of Methane in the Gas Mixture
Since the mixture is composed of 75% methane, the mass of methane in the mixture can be calculated as:
Mass of methane = 75% of 100g = 75g

Step 3: Calculate the Mass% of Methane in the Gas Mixture
The mass% of methane in the gas mixture can be calculated by dividing the mass of methane by the total mass of the mixture and multiplying by 100:
Mass% of methane = (75g / 100g) x 100% = 75%
Therefore, the mass% of methane in the gas mixture is 75%. This means that 75% of the total mass of the gas mixture is composed of methane.
