Question

How to find molecular weight for a compound?

Answer 1

let's do this using an example

let's take glucose as our compound

First find the chemical formula of the given compound.

the chemical formula of glucose is C6H12O6.

now find the atomic weight of individual element in the compound

weight of 1 carbon atom is 12u. so weight of 6 carbon atoms is 6×12= 72u.

weight of 1 Hydrogen atom is 1u. so weight of 12 Hydrogen atoms is 12u.

weight of 1 oxygen atom is 16u. so weight is 6 oxygen atoms is 6×16= 96u.

Now, add all the weights of elements .i.e 72+12+96 = 180u

So, here you have it the molecular weight glucose and you can calculate the molecular weight of any compound by this method.
