of weigh and of weigh The molar mass of and molar mass of in are :
Molar Mass -
The mass of one mole of a substance in grams is called its molar mass.
Molar mass of water = 18 g mol-1
Mole Concept -
One mole is the amount of a substance that contains as many particles or entities as there are atoms in exactly 12 g (or 0.012 kg) of the 12C isotope.
one mole = 6.0221367 X 1023
Let atomic mass of & atomic mass of
Solving equations (I) & (II), simultaneously, we get:
