Let's calculation the variety of molecules chairman in each of the following for a 6.37 mole of carbon monoxide and their 6.2 times 10 come the 23rd molecules Permal and also this main Guild 3.8, 3 times 10 come the 24th molecule of carbon monoxide because that be. We have 6.37 grams of carbon monoxide. But first take root. This too. Uh, moles and also molar mass. It would be 30.0 grams promote and also then in one an ext we have actually 6.2 times 10 to the 23rd molecules, and this will work-related out to it is in 1.28 times 10 to the 23rd molecule of carbon monoxide. Because that C, we have, uh, 2.62 time 10 to the negative six grams that water. And this would provide me first molar fixed of waters 18 grams every mole 612 times 10 to the 23rd molecules promote. This would yields 8.76 times 10 come the 16 molecule of water de 2.62 time 10 come the an adverse six moles of H 20 6.2 10 to 23rd molecules. Permal. This would give me 1.58 times 10 80 18 molecule of water and lastly because that E. We have 5.23 grams of benzene C six h six molar fixed of benzene IHS, 78.0 grams per mole and then in a mole 6.2 time 10 come the 23rd molecule in this would certainly deal support for three I can't psychic 4.4 times 10 come the 22 molecule of Benzie.
