A sample of ethane `(C_(2)H_(6))` gas has the same mass a `1.5 xx 10^(20)` moleucles of methane `(CH_(4))`. How many `C_(2)H_(6)`. How many `C_(2)H_(6)` molecules does the sample of gas contain?

Text Solution

AI Generated Solution

To solve the problem, we need to find out how many molecules of ethane (C₂H₆) are present in a sample that has the same mass as 1.5 x 10²⁰ molecules of methane (CH₄). ### Step-by-Step Solution: 1. **Calculate the Molar Mass of Methane (CH₄)**: - The molar mass of methane can be calculated as follows: - Carbon (C) has an atomic mass of 12 g/mol. - Hydrogen (H) has an atomic mass of 1 g/mol. ...
