Let's calculation the number of molecules chairman in each of the adhering to for a 6.37 mole of carbon monoxide and also their 6.2 time 10 to the 23rd molecule Permal and this main Guild 3.8, three times 10 come the 24th molecule of carbon monoxide because that be. We have 6.37 grams the carbon monoxide. But an initial take root. This too. Uh, moles and molar mass. It would certainly be 30.0 grams promote and also then in one an ext we have 6.2 times 10 come the 23rd molecules, and this will job-related out to it is in 1.28 times 10 come the 23rd molecule of carbon monoxide. Because that C, we have, uh, 2.62 times 10 come the an unfavorable six grams that water. And this would provide me an initial molar mass of waters 18 grams per mole 612 time 10 to the 23rd molecules promote. This would yields 8.76 times 10 to the 16 molecules of water de 2.62 time 10 come the an unfavorable six mole of H 20 6.2 10 come 23rd molecules. Permal. This would offer me 1.58 times 10 80 18 molecules of water and also lastly for E. We have 5.23 grams the benzene C six h six molar mass of benzene IHS, 78.0 grams every mole and then in a mole 6.2 times 10 come the 23rd molecules in this would deal support for three I can't psychic 4.4 times 10 come the 22 molecule of Benzie.
