My brother helped me out with this and he put this 3.45 e+9
To get the molecules contained in liquid ethanol, we multiply the density to the given volume, that is equal to 0.789 g ethanol. In this case, we divide by molar mass and multiply by the constant, Avogadro's number. The answer is 1.033 x 10^22 molecules.
Answer:
Hi AP Chemistry student. It seems this experiment is impossible. Sterling Silver cannot be separated so easily with this pathetic equipment. However, if one were to carry this experiment out, I would assume they would need to put the alloy in the graduated cylinder and then somehow filter the silver out through filter paper or Buchner funnel. taking the mass with a stir rod is also helpful for the mass percent calculation. I hope this helps you out, good luck in Mrs. Fischer's class :)
Explanation:
Answer is gas for sure and I think it’s ice for question 2
