There can only be a net ionic reaction when a precipitate is formed as the two solutions are mixed together.
Best Answer: <span> Moles of O2 =3.01 x 10^23 / 6.02 x 10^23 = 0.500
mass O2 = 0.500 mol x 32 g/mol= 16 g </span>
Mass = 124 g
volume = 17 cm³
density = mass / volume
Therefore:
D = 124 / 17
D = 7.294 g/cm³
From erosion i think good luck :D
