Interpretation:
The empirical formula of
Concept Introduction:
The formula of the chemical compound in which atoms are present in simple positive integer ratio is said to be empirical formula. This formula only gives the proportions of the elements but doesn’t give the actual number of atoms present in the compound.
(b)
Interpretation:
The molecular formula of BARF should be calculated.
Concept Introduction:
The formula of the chemical compound in which atoms are present in simple positive integer ratio is said to be empirical formula. This formula only gives the proportions of the elements but doesn’t give the actual number of atoms present in the compound.
Molar mass of the compound or element is equal to the mass in grams of one mole of that molecule or substance. It is a measured in g/mole.
Molar mass of the compound is calculated by the addition of molar masses of atoms in g/mole present in that compound.
