8. The mass of 4.56 moles of sulfur dioxide? Well, that depends on how much sulfur dioxide decided to weigh itself that day!

9. The mass of 4.56 molecules of sulfur dioxide? Honestly, I tried asking them for their weight, but they just vanished into thin air. Guess they're enjoying their molecular vacation!

10. How many formula units are in 0.456 grams of Ca3(PO4)2? I counted exactly 0.456 formula units. They were hiding, playing hide and seek with me!

11. How many moles are in 1.5 x 10^23 atoms of fluorine? Let's see... That's enough fluorine atoms to throw a really wild party in a tiny beaker! You've got yourself 1.5 x 10^23 moles of fun!

12. The mass of 2.80 x 10^23 molecules of CO2? Well, I gotta give CO2 some credit, it really knows how to carb it up! The mass would be approximately 10 gazillion grams. Just kidding! It's actually around 7.84 grams. But who's counting, right?

To answer these questions, you will need to use the concept of molar mass and Avogadro's number. Here's how you can find the answers:

8. To calculate the mass of a given number of moles, you need to multiply the number of moles by the molar mass of the substance. The molar mass of sulfur dioxide (SO2) can be calculated by adding the atomic mass of sulfur (S) to twice the atomic mass of oxygen (O). The atomic masses of S and O can be found on the periodic table. Once you have the molar mass, you can multiply it by the number of moles to get the mass.

9. To find the mass of a given number of molecules, you will need to use both Avogadro's number and the molar mass of sulfur dioxide. Avogadro's number represents the number of molecules in one mole of a substance. First, calculate the number of moles by dividing the given number of molecules by Avogadro's number. Then, multiply the molar mass by the number of moles to find the mass.

10. To determine the number of formula units, you need to convert the given mass of Ca3(PO4)2 to moles using the molar mass of the compound. Then, divide the number of moles by the Avogadro's number to get the number of formula units.

11. Again, you will need to use Avogadro's number to convert the given number of atoms to moles. Divide the number of atoms by Avogadro's number to get the number of moles.

12. Similar to question 9, you will need to calculate the number of moles by dividing the given number of molecules by Avogadro's number. Once you have the number of moles, you can multiply it by the molar mass of CO2 to find the mass.

Remember to consult the periodic table for atomic masses and use Avogadro's number (6.022 x 10^23) when appropriate.

8. moles = grams/molar mass. Solve for grams.

9. There are 6.022E23 molecules in a mole; therefore, 4.56 molecules = (4.56/6.022E23) = # moles SO2. Follow 9 to determine mass.

You should be able to do the others now.
