Answer
The molecular formula for an alkane with 10 carbon atoms is
.
Explanation
## Step 1:The general formula for an alkane is
, where
is the number of carbon atoms.## Step 2:In this case, we need to find the molecular formula for an alkane with 10 carbon atoms. Thus,
.## Step 3:Substitute
into the general formula to calculate the number of hydrogen atoms.### \(\mathrm{H}_{2n+2} = 2(10) + 2 = 20 + 2 = 22\)## Step 4:Therefore, the molecular formula for an alkane with 10 carbon atoms is
