Question

What is the empirical formula of butane gas if it consists of 82,76% of carbon and 17,24% hydrogen

Answer 1

[AI-generated answer — Bot GPT 3.5]

To find the empirical formula, we need to convert the percentages of each element to moles.

Assuming we have 100g of the gas:
- Carbon: 82.76g * (1 mol/12.01g) = 6.89 moles
- Hydrogen: 17.24g * (1 mol/1.008g) = 17.09 moles

The ratio of moles between carbon and hydrogen is approximately 1:2. Therefore, the empirical formula of butane gas is CH2.
