    Hey MAD 2 Hydrogen atoms + 1 oxygen atom = H2o

    3H2O : 9 atoms

    5H2O = 15 atoms

    for second part

    C6H12O6
    Total atoms in 1 molecule = 6 + 12 + 6 = 24

    2C6H12O6
    6 carbon atoms, 12 helium atoms, and 6 oxygen atoms then you have 24 atoms times the 2 at the beginning making 48 atoms
