You cannot calculate the solubility of X in water at 26 degrees Celsius because you do not know whether the solution formed by dissolving the crystals in 3.00 liters of water is saturaed or not.

The only way to determine the solubility of the compound X is by dissolving the crystals in certain (measured) amount of water and making sure that some crystals remain undissolved, as a solid on the bottom of the beaker.

Next, you should filter the solution to remove the undissolved crystals. Then, weigh the solution, evaporate, wash, dry, and weigh the crystals.

Then you have the mass of the crystals dissolved and the mass of the solution which will let you calculate the mass of pure water, and then the solubility.

You are performing an experiment in a lab to attempt a new method of producing pure elements from

9966 [12]

Answer:

Molybdenum

Explanation:

Since, the atomic mass of the elements is a characteristic property of the elements, you can use the data given, number of moles and mass in grams of the product, to calculate the atomic mass of the product, and then compare with the atomic masses of the elements (information foun in any periodic table).

1) Atomic mass of the product:

Atomic mass = mass in grams / number of moles

Atomic mass = 604.4 g / 6.3 mol = 95.94 g/mol ≈ 94.9 g/mol (rounded to three significant figures)

2) Periodic table:

Molybdenum, Mo, the element with atomic number 42, has atomic mass equal to 95.94 g/mol.

3) Conclusion:

So, you can conclude safely that the element you have produced is Molybdenum.
