One mole of different compounds have different masses but have same number of molecules because that is the definition of a mole - a mole is about 6.022x1023 molecules of any particular material - and is normalized to the mass of Carbon-12.
Carbohydrates are macro molecules made by bonding a large number of glucose molecules. They are organic compounds. They contain elements Carbon, hydrogen and oxygen.
An 'atom' contains only protons, neutrons and electrons, and the number of those determine what element or isotope of that element the atom is. It is therefore impossible to say an atom can 'contain' an element.
Carbohydrates are large molecules. They are made up of a large number of glucose molecules bond together. So they are not elements, they are compounds.
Isotopes of the same element have the same number of protons (atomic number) but differ in number of neutrons (hence atomic masses).
Both nitrogen and oxygen exist at standard temperature and pressure as diatomic molecules. Therefore, the relative masses of equal numbers of molecules of the substance will the same as the ratios of their atomic masses, which are 15.9994 for oxygen and 14.0067 for nitrogen. The mass of oxygen that contains the same number of molecules as 42 g of nitrogen is 42(15.9994/14.0067) or 48 g, to the justified number of significant digits.
These compounds have equal molar masses.
They are different molecules--They are, however, related by the law of multiple proportions. This law states that when different compounds are formed by a combination of the same elements, different masses of one element combine with the same relative mass of the other element in a ratio of small whole numbers.

They are different compounds with different molecules:- the chemical formula of glucose is C6H12O6- the chemical formula of sucrose is C12H22O11

It is often mentioned that water can dissolve a huge variety of compounds of varying chemical characteristics. Declaring a strict number of such molecules would be almost impossible. It should be said that these compounds cannot be put into a single category. At first, let's take a look at ionic compounds. Being a polar solvent, water can dissolve many ionic compounds by dissociating them into seperate ions and creating hydrated spheres. Eventhough, there are some ionic lattices that do not dissolve, which we usually call as precipitates. When it comes to covalent compounds, many ones with asymmetric polar bonds are dissolved in water such as alcohols, amines etc. In rare cases, non polar compounds also partially dissolve in water, such as bromine and iodine. Generally, it can be also said that, molecules with relatively higher molecular masses, show less tendency to dissolve in water.
AnswerOne reason for the very large number of organic molecules (compared to the total number of inorganic compounds) is due to constitutional isomerism. Constitutional isomerism are different compounds that have the same molecular formula but differ in their connectivity, that is, in the sequence in which their atoms are bonded together.
Different atoms and elements that have different number of protns, neutrons and electrons.Duh!
An 'atom' contains only protons, neutrons and electrons, and the number of those determine what element or isotope of that element the atom is. It is therefore impossible to say an atom can 'contain' an element.
He published a paper called (translation) "Essay on determination the relative masses of the elementary molecules of bodies and the proportions by which they enter these combinations". It is from his work that we get 'Avogadro's Number' the number of molecules/atoms in a mole.
Only if they are hydrates. Different compounds can combine with a discrete number of water molecules, such as, for example copper.
Carbohydrates are large molecules. They are made up of a large number of glucose molecules bond together. So they are not elements, they are compounds.
Different atoms of the same element possessing different atomic masses but having same atomic number are known as Isotopes. Since the isotopic atoms have the same atomic number, they must contain an equal number of protons. As their atomic masses are different, there must be a difference in the number of neutrons they possess. They will show similar chemical properties but their physical properties will be different due to different masses.
