you have to find 2g of oxygen has how many moles and also find the number of moles of the elements given in option. match the number of moles of oxygen with the number of moles from option . :) if you still have any doubt do let me know :)

yes 1 mol contains àvogadro's number of atoms. so you find number of moles and multiply it with àvogadro's number. since àvogadro's number is a constant value so you need to find only number of moles
