The molar mass is the mass of one mole of a substance in g/mol. In order to determine the molar mass, you must know the chemical formula and have access to a Periodic Table. Let's use water as an example. The chemical formula for water is H2O. To find the molar mass, multiply the atomic weight on the periodic table in grams/mol for each element times the subscript for the element, and add the molar masses.
H: 2 x 1.00794g/mol = 2.01588g/mol
O: 1 x 15.9994g/mol = 15.9994g/mol
------------------------------------------------
Molar mass = 18.0153g/mol

Why and how inorganic compounds dissolve in water?
Like dissolves like. Polar inorganic compounds will dissolve in polar solvents like water or alcohol.
What is a water hydrophilic?
Compounds that like water.
How do you calculate the equivalent weight of compound?
the sum of the atomic weights for all the atoms in the formula
Does water only dissolve inorganic compounds?
Water can dissolve organic compounds that are capable of hydrogen bonding. This would be organic compounds that contain a hydroxy group or amines. Remember that amines will not form hydrogen bonds in aromatic groups and their solubility in water decreases with increase in carbon atoms.
Are organic compounds less soluble in water?
Organic compounds have to be defined as best as possible to determine what is soluble in water. Organic compounds are molecules composed with carbons--pure hydrocarbons like octane would not be soluble in water. Organic compounds can also have electronegative molecules in it. Dichloroethane, methanol, ethanol, etc are soluble in water. However, most organic compounds will more likely have low solubility in water, since increasing the number of carbon molecules in any compound drastically reduces water solubility.
How water disssolves ion compounds and polar compounds?
Like dissolves like. Water is polar solvent and hence it dissolves ionic and polar compounds.
Why and how inorganic compounds dissolve in water?
Like dissolves like. Polar inorganic compounds will dissolve in polar solvents like water or alcohol.
What is a water hydrophilic?
Compounds that like water.
What releases ions when dissolved in water?
Soluble ionic compounds like NaCl, and some covalent compounds like HCl(g) which will dissociate in water.
How do you calculate the equivalent weight of compound?
the sum of the atomic weights for all the atoms in the formula
what compounds in the liquid stage can be considered an electrolyte?
generally ionic compounds like those compounds which dissolves into ions in water like NaCl,NaOH etc.
How is an acid similar to ionic compounds?
Although Acid is covalently bonded they break apart in water like ionic compounds. How ever they do not conduct electricity like ionic compounds
Why are ionic compounds insoluble in organic compounds?
It isn't strictly true, but generally ionic compounds are not highly soluble in organic solvents because ionic compounds need a highly polar solvent to dissolve well (such as water) and in general organic compounds are not as polar as water. Remember, like dissolves like. However, many ionic compounds are very soluble in a variety of organic solvents, just not as much as in water.
What happens when covalent compounds are mixed with water?
If the compounds are polar covalent then they are soluble in water . If they contain high electronegative element like F,O and N ,water can form inter molecular hydrogen bond with those compounds.
What type of compounds can dissolve in water?
The general rule for solvation is like dissolves like. Water is a very polar molecule. Thus, water best dissolves polar substances, including ionic and polar covalent substances.
Do all compounds contain water?
No, not all compound contain water like carbon dioxide, it does have water in it
Does water only dissolve inorganic compounds?
Water can dissolve organic compounds that are capable of hydrogen bonding. This would be organic compounds that contain a hydroxy group or amines. Remember that amines will not form hydrogen bonds in aromatic groups and their solubility in water decreases with increase in carbon atoms.
