ok so i need to find how many atoms make up the earth. the average atomic mass of the atoms is 14g/mol. avogadro's number gives the number of atoms in a mole. so what atom do i take?? carbon or something??
Take the mass of the earth, in grams, then divide by 14g/mol, that will give the mol on Earth, then multiply by avag number.
