Which observations would have been consistent with Marie Curie's work? Check all that apply.
O One gram of a uranium salt has twice the radioactivity as two grams of the same salt.
One mole of uranium chloride has the same radioactivity as one mole of uranium sulfate.
O One mole of solid uranium chloride has the same radioactivity as one mole of uranium chloride
dissolved in a solvent
O T wo liters of a solution of uranium dissolved in a solvent have twice the radioactivity as one liter of
the same solution.
