Let's calculate the number of molecules president in each of the adhering to for a 6.37 moles of carbon monoxide and also their 6.2 times 10 to the 2third molecules Permal and this week Guild 3.8, 3 times 10 to the 2fourth molecules of carbon monoxide for be. We have 6.37 grams of carbon monoxide. But initially take root. This as well. Uh, moles and molar mass. It would be 30.0 grams promote and then in one more we have 6.2 times 10 to the 23rd molecules, and also this will work-related out to be 1.28 times 10 to the 23rd molecules of carbon monoxide. For C, we have, uh, 2.62 times 10 to the negative six grams of water. And this would certainly provide me initially molar mass of waters 18 grams per mole 612 times 10 to the 23rd molecules promote. This would certainly returns 8.76 times 10 to the 16 molecules of water de 2.62 times 10 to the negative 6 moles of H 20 6.2 10 to 23rd molecules. Permal. This would certainly offer me 1.58 times 10 80 18 molecules of water and finally for E. We have actually 5.23 grams of benzene C 6 h 6 molar mass of benzene IHS, 78.0 grams per mole and then in a mole 6.2 times 10 to the 23rd molecules in this would certainly deal assistance for 3 I can't remember 4.4 times 10 to the 22 molecules of Benzie.
