Dr.Bob the question Ihad reposted (NOT the old one
1ml isopentyl alcohol + 1.5ml glacial acetic acid + 3 drops sulfuric acid=> isopentyl acetate to calculate the theoretical yield.. I know that the acetic acid is in excess but how would I calculate the theoretical yield? is it just find moles acetic acid (know excess) and ...

One simple way to do this is calculate how many moles of HBr are in 1ml Moles=.001L/22.4L So, you have the number of moles of HBr. Since Br2 was used to make it, it must be 1/2 that number of moles. convert that to grams.

What is the mass in grams of 1.02X10^24 molecules of NaCl?
Tuesday, March 11, 2008 at 2:28pm by J
1 mole contains 1.02 x 10^23 molecules. Hence you can calculate the number of moles 1.02 x 10^24 molecules represents. If you calculate the mass in grams of one mole of NaCl from the atomic masses, you can find the answer.
