Answer to Question #3185 in Inorganic Chemistry for haley

Question #3185
How do you get molar mass?
Expert's answer
You should know the molar mass of each chemical element in the compound. M(el)
Then you should count how many times each element appears in the compound. N
Multiply M(el) by N respectively M1*N1, M2N2, M3N3 for each element and then add these numbers.

For example:
M(K) = 39 g/mol, M(Mn) = 55 g/mol, M(O) = 16 g/mol.
There are four atoms of the Oxigen in this compound, thus
M(KMnO4) = 1* 39 + 1 * 55 + 4 * 16 = 158 g/mol.
