What is the formula of an alkane containing 20H?
Question
What is the formula of an alkane containing 20H?
Solution 1
The general formula for alkanes is CnH2n+2.
Given that the number of hydrogen atoms (H) is 20, we can set up the equation 2n + 2 = 20 to find the number of carbon atoms (C).
Solving for n gives:
2n = 20 - 2 2n = 18 n = 18 / 2 n = 9
So, an alkane with 20 hydrogen atoms would have 9 carbon atoms.
Therefore, the formula of the alkane is C9H20.
Solution 2
The general formula for alkanes is CnH2n+2.
Given that the number of hydrogen atoms (H) is 20, we can set up the equation 2n + 2 = 20 to find the number of carbon atoms (C).
Solving for n gives us n = 9.
Therefore, the formula for an alkane with 20 hydrogen atoms is C9H20.
