A glucose molecule contains carbon hydrogen and oxygen in the ratio 6 to 12 to 6 What is the molecular formula for glucose?
Kaylabeth
Molecular formulas can not be determined from information about atomic ratios only. If the ratios stated are atomic ratios, then the empirical formula of the compound is CH2O. If the questioner meant, "A glucose molecule contains 6 carbon atoms, 12 hydrogen atoms, and 6 oxygen atoms ...", the molecular formula is C6H12O6.

How does the molecular formula for sucrose compare to maltose?
Both sucrose and maltose have the same molecular formula, C12H22O11. What makes them different, however, is the structure these atoms take in the molecule.
What is the formula for adenine?
The empirical formula for adenine is CHN.The molecular formula is C5H5N5.
What is the molecular formula of caproic acid?
The molecular formula of caproic acid is C6H12O2.Structurally, it has an unbranched hydrocarbon chain terminating in a carboxyl group:C5H11COOH. It is also known as hexanoic acid.The molecular formula for caproic acid is C6H12O2. Caproic acid is also called hexanoic acid.
What is the mass of one molecule of glucose?
Each atom has its own RELATIVE MASS.This is the mass of each atom in comparison to carbon.C6H12O6 is the formula of a glucose molecule.C6 means there are 6 carbon atoms. 1 carbon atom has a mass of 12.So 6 * 12 = 72H12 means there are 12 hydrogen atoms. 1 hydrogen atom has a mass of 1.So 12 * 1 = 12O6 means there are 6 oxygen atoms. 1 oxygen atom has a mass of 16.So 6 * 16 = 9672 + 12 + 96 = 180So a molecule of glucose has a relative molecular mass of 180.Hope this helps
Why is the amine group of an amino acid toxic to cells?
The amino group of an amino acid contains the elements Nitrogen and Hydrogen. By itself, it is not toxic to cells. But after deamination where the amino group is removed from the amino acid, the amino group is then converted into ammonia. Ammonia is toxic to cells, and also contains Nitrogen and Hydrogen, but it has a different chemical formula from the amino group.
What does sulphuric acid contains?
sulphur and hydrogen the molecular formula is H2SO4
What is the relative mass formula of hydrogen gas?
The molecular mass of hydrogen gas is 2. A molecule of hydrogen gas contains two hydrogen atoms covalently bonded. Since each hydrogen atom has an atomic mass of 1 (as we can derive from the Periodic Table of Elements), the molecular mass of hydrogen gas as a molecule is 1 + 1 = 2.
How many hydrogen atoms does a caffeine molecule have?
Caffeine has the molecular formula C8H10N4O2So there will be ten hydrogen atoms.
Is h2 a atom or molecular?
H2 is the molecular formula for hydrogen gas; H is the chemical formula for one atom of hydrogen, whether it be gas, liquid, or solid.
What is the advantage of using a structural formula over a molecular formula?
A molecular formula indicates the numbers of atoms of each element in the molecule, but a structural formula also indicates the arrangement of the atoms in the molecule. For example, H2O is the molecular formula for water, but H-O-H is the structural formula, showing how the hydrogen and oxygen atoms are arranged in the molecule.
The molecular mass of a compound is 63.008 amu contains Hydrogen and Oxygen and Nitrogen elements It molecular formula is?
HNO3
The chemical formula H20 means water molecule contains one?
It contains one molecule of oxygen and two molecules of hydrogen.
How many hydrogen atoms are in a molecule of water (H2O)?
2The molecular formula of water is H2O. It contains 2 atoms of hydrogen.H2O =2 atoms of hydrogen.
What is the molecular formula of the saturated hydrocarbon whose 1 molecule contains 8 hydrogens?
The chemical formula of octane is C8H18.
Why does hydrogen gas have the symbol H2?
The symbol for atomic hydrogen is H. But hydrogen as a gas molecule consists of two hydrogen atoms, so the formula for molecular hydrogen is H2.
How many hydrogen atoms does tryptophan contain?
The molecular formula for tryptophan is C11H12N2O2, so it contains 12 atoms of hydrogen.
Is adenosine triphosphate an organic molecule?
An organic compound is a molecule that contains carbon and other organic elements such as sulfur, hydrogen, and nitrogen. The molecular formula for ATP is C10H16N5O13P3. This would conclude that ATP is an organic molecule. It is also naturally made, which is one of the characteristics of an organic molecule.
