Answer:

There are:

  • 2'531,500 g Cu
  • 1'269,500 g S

Explanation:

First <u>calculate the percentage of Cu and S in the compound</u>:

  • Total mass = 76.84 g + 38.53 g = 115.37 g
  • % metal (Cu) = 76.84/115.37 * 100% = 66.6%
  • % metal (S) = 38.53/115.37 * 100% = 33.4%

<em>These percentages will remain the same no matter how much of the compound we analyze</em>.

Now we calculate the grams of Cu and S in 3801 kg of the compound:

  • kg Cu = 3801 kg * 66.6/100 = 2531.5 kg Cu
  • g Cu = 2531.5 kg * 1000 = 2531500 g Cu
  • kg S = 3801 kg * 33.4/100 = 1269.5 kg S
  • g S = 1269.5 kg * 1000 = 1269500 g S

A chemist determined by measurements that 0.050 moles of aluminum participated in a chemical reaction. Calculate the mass of alu
Law Incorporation [45]

Answer:

13.5 g

Explanation:

This question is solved easily if we remember that the number of moles is obtained by dividing the mass into the atomic weight or molar mass depending if we are referring to elements or molecules.

Therefore, the mass of aluminum in the reaction will the 0.050 mol Al times the atomic weight of aluminum.

number of moles = n = mass of Al / Atomic Weight Al

⇒ mass Al = n x Atomic Weight Al = 0.050 mol x 27 g mol⁻¹

                                                         = 13.5 g

We have three significant figures in 0.050 and therefore we should have three significant figures in our answer.
