We just have to multiply atmoic mass with no. of atoms
eg molar mass of h2o will be 1*2+1*16=18u
eg molar mass of h2o will be 1*2+1*16=18u
pmtibrahim:
oh
but
: ) : )
wait
I will send a doubt
how is heliums molar mass is 4?
becoz atomic mass of he is 4 and no. of atoms of helium is 1 so, 4*1 = 4
oh
I see

Hey!
________________________
Molar mass is defined as mass of a given substance divided by amount of substance.
Molar mass = Atomic mass of substance × number of atoms.
For example- Find molar mass of oxygen?
Molar mass = Atomic mass of oxygen × Number of atoms
M= 16×2
M= 32 g
As, number of atoms in oxygen is 2 (O2) and mass of 1 oxygen atom is 16.
