Methanol has a single carbon it its center with , 3 hydrogens and 1 hydroxyl (OH) group attached for a total of:
1 carbon atom
4 hydrogen atoms
1 oxygen atom
One carbon atom attached with three hydrogen atoms and OH (alcohol) functional group
The number of hydrogens equals 2x the number of carbon atoms, plus 2 extra hydrogens.
3 molecules of methanol (CH3OH) contain a total of 21 atoms. Each methanol molecule consists of 5 atoms: 1 carbon atom, 4 hydrogen atoms, and 1 oxygen atom. Therefore, 3 molecules would have 21 atoms (5 atoms x 3 molecules + 1 atom for the extra carbon in the last molecule).
A pentane molecule has 5 carbon atoms and 12 hydrogen atoms.
An alkane with six carbon atoms would be hexane (C6H14). Since each carbon atom is bonded to two hydrogen atoms in an alkane, you would have 6 carbon atoms x 2 hydrogen atoms per carbon = 12 hydrogen atoms.

There are four atoms of hydrogen in each molecule of methanol.
4 H-atoms r in Methanol
The number of hydrogens equals 2x the number of carbon atoms, plus 2 extra hydrogens.
3 molecules of methanol (CH3OH) contain a total of 21 atoms. Each methanol molecule consists of 5 atoms: 1 carbon atom, 4 hydrogen atoms, and 1 oxygen atom. Therefore, 3 molecules would have 21 atoms (5 atoms x 3 molecules + 1 atom for the extra carbon in the last molecule).
Decane has 10 carbon atoms and 22 hydrogen atoms.
A pentane molecule has 5 carbon atoms and 12 hydrogen atoms.
there are two Carbon Atoms and six Hydrogen atoms
A non cyclic alkane always has a number of hydrogen atoms equal to 2c + 2, where c is the number of carbon atoms. Therefore, hexadecane, an alkane with 16 carbon atoms, will have 34 hydrogen atoms.
An alkane with six carbon atoms would be hexane (C6H14). Since each carbon atom is bonded to two hydrogen atoms in an alkane, you would have 6 carbon atoms x 2 hydrogen atoms per carbon = 12 hydrogen atoms.
Ethanol has 2 carbon atoms and 3 hydrogen atoms attached to one of those carbon atoms with 2 hydrogen atoms and one hydroxyl (OH) group attached to the other - for a total of: 2 carbon atoms 6 hydrogen atoms 1 oxygen atom.
