How many moles can be found in 3.2526443x1023 atoms in Bismuth?

6.02 x 10^23 atoms = 1 mole

3.2526443 x 10^23 / 6.02 x 10^23 = 0.54 mole

the law of conservation of mass states that in a chemical reaction, the total mass of reactants is equal to the total mass of products. because atoms are only rearranged in a chemical reaction, there must be the same number of sodium atoms and chlorine atoms in both the reactants and products

i think it is d. e because the next one is igneous.
