Question 5 is the second one.
Answer:
Explanation:
you would have to look more around the page, for example look at some ways that you can right down.
Molarity is defined as the number of moles of solute in 1 L of solution
number of moles of NaI - 10.7 g / 150 g/mol = 0.0713 mol
there are 0.0713 mol in 0.250 L
we need to find the number of NaI moles in 1 L
if 0.250 L contains - 0.0713 mol
then 1 L contains - 0.0713 mol / 0.250 L = 0.285 mol/L
molarity is 0.285 M
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 :)
