If it is saturated open chain hydrocarbon then hydrogen must be 244.

For a hydrocarbon with 121 carbons, the general formula would be CₙH₂ₙ₊₂. Therefore, there would be 123 hydrogens in this hydrocarbon (2 more than the number of carbons).

How many atoms are there in a molecule of ethylene?
Ethylene (C2H4) has two carbons and four hydrogens making 6 atoms.
Determine How Many hydrogen atoms a compound has if its a hydrocarbon and its carbon atoms skeleton is c c-c c?
Hydrocarbon rule.2n + 2You have 4 carbons. I assume alkane.10 hydrogens.C4H10
How many atoms make up 1 molecular of vinegar?
Vinegar is acetic acid or CH3COOH and there are totally 8 atoms (2 carbons, 2 oxygens and 4 hydrogens) in one molecule of vinegar.
How many Hydrogen atoms are in an Alkane with 7 Carbon atoms?
Alkanes have the general formula of CnH2n+2 so for 12 carbons, that would be 2x12 + 2 = 26 hydrogen atoms.
One molecule has how many atoms of hydrogen?
Answer: Molecules do not necessarily have any hydrogen atoms (e.g. NaCl has only sodium and chlorine and no hydrogen)The lowest number of hydrogens possibly present is one. This occurs in compounds like hydrogen chloride (HCl).Many molecules have two hydrogens, the simplest is hydrogen gas (H2)After this it's open season on hydrogens. Complex hydrocarbons (for example, polyethylene and heavy alkane oils) can have several hundred carbons each with two hydrogens and two extra to cap the ends (general formula : CnHn+2)
How many hydrogens are present on an alkane with 20 carbons?
An alkane with 20 carbons will have 42 hydrogens. This can be calculated using the formula 2n+2, where n is the number of carbons (C) in the alkane. So for an alkane with 20 carbons, the number of hydrogens would be 2(20) + 2 = 42.
How many atoms are there in a molecule of ethylene?
Ethylene (C2H4) has two carbons and four hydrogens making 6 atoms.
How many hydrogens does 2 octyne contain?
2-octyne contains 16 hydrogens. Each carbon atom in the alkyne chain is connected to two hydrogen atoms, except for the end carbons which are connected to three hydrogens.
How many hydrogens are on a saturated hydrocarbon with 4 carbons?
A saturated hydrocarbon with 4 carbons, which is a butane molecule, will have 10 hydrogen atoms. The general formula for calculating the number of hydrogen atoms in an alkane molecule is 2n + 2, where n is the number of carbon atoms.
In alkanes carbon is bonded to how many other atoms?
Four. A terminal carbon in an alkane is bonded to 3 hydrogens and 1 carbon, while a middle carbon is bonded to 2 hydrogens and 2 carbons.

What do hydrogen and carbon make?
When hydrogen and carbon combine, they can create various hydrocarbons, such as methane (CH4) or ethane (C2H6). These compounds are the basis for many organic molecules found in nature, including fossil fuels and organic materials.
How many carbon atoms does propane have?
there are 8 hydrogen atoms present in propane. There is 8 hydrogen atoms in propane, Each carbon has a valency of 4, 4 bonds with other atoms. Hydrogen has valency of 1. the general formula for alkanes is CnH2n +2 (n means number of that atom.) so to find how many hydrogens there with, say, 50 carbons you would do CnH2n + 2= C50H102. :)
How many oxygens are in glucose?
C6H12O6 is glucose. There are six carbons, twelve hydrogens and six oxygens in each molecule.
How many resonance structure benzene have?
Benzene has two resonance structures, where the double bonds can be delocalized around the ring to give it stability. This resonance results in the alternating single and double bond structure of benzene.
How many carbons does propane have?
Three. Propane is C3H8, a (hydrocarbon) molecule containing 3 carbon atoms and 8 hydrogen atoms.
What fatty acids do not have double bonds beween carbons?
If there are no double bonds, then carbon will take up as many hydrogens as it can, two (three on the ends). Because there are more hydrogens bonded, they are referred to as "saturated" lipids. Unsaturated lipids have double bonds between the carbons and hydrogens. When there is a double bond, one carbon only bonds with one hydrogen - "unsaturated" lipids. The double bonds cause "kinks" in the fatty acid tails, so it is more difficult to "pack" them together. For this reason, they do not solidify at room temperature. However, saturated lipids may solidify at room temperature -- this is how you distinguish between saturated and unsaturated lipids by sight. Examples of saturated lipids (having no double bonds between carbons and hydrogens) are animal fats. "Saturated fats" is a synonym for animal fat on nutritional labels.
