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.
