1 mol of Gas A (molar mass=64g/mol ) escapes from a container through a hole in 8 seconds. A mixture of 0.8 mol gas A and 0.2 mol gas B, escapes from an identical container through same hole (at same T and P) in 9 seconds. What is the molar mass of gas B?
Answers
Answer:
The rate of effusion is directly proportional to the mole fraction and inversely proportional to the square root of molar mass.

Hence, the time required to effuse same volume of methane gas is 40 sec.
Answer:
Inversely correlated with the square root of molar mass is the rate of effusion, which is directly proportional to the mole fraction. Consequently, it takes 40 seconds to release the same volume of methane gas.
Explanation:
What is a methane gas?
- Chemically, methane has the formula CH4, and it is a substance. The most fundamental component of natural gas, it is a group-14 hydride and the simplest alkane.
- Colorless, odorless, and very combustible is the gas known as methane (CH4). Carbon and hydrogen make up its makeup. According to the US Environmental Protection Agency, it is also a powerful greenhouse gas, meaning it contributes to increased heat and so has an impact on climate change.
- A combustible gas without an odor or color, methane. In order to provide heat and light, it is mostly utilized as fuel. Making organic compounds with it is another use.
- It is common in landfills, marshes, septic tanks, and sewers to find methane, which can be produced as natural materials decompose.
