What is mole and what is the formula to calculate molecule in the substance
To calculate the number of molecules in ‘x’ grams of a compound ‘s’, we are going to take help of the compound’s molar mass. Firstly, obtain the number of moles of s by dividing x by the molar mass of s.
Number of Moles =( GivenMassofCompound)/(MolarMassofCompound
Then multiply the number of moles of s by Avogadro's Constant 6.022×10236.022×10^23; which is the number of atoms present in 1 mole of a substance. Therefore, you finally have
Number of Molecules= NumberOfMoles×6.022×10^23
