<center><b>Two Step Mole Problems Handout 3</b></center><br> <br> Answer the following problems show all work. <i>For the purpose of this handout, all gases are assumed to be at <nowiki>STP</nowiki> (standard temp & pressure).</i><br> <br> <b>Answers should be completed on separate sheets (no more than 5 problem per sheet.) In other words, need to complete work on 2 or more sheets of paper ( a sheet of paper is front and back.)</b> <br> 1. How many liters @STP of F<sub>2</sub> if I have 56.1g of this compound.<br> 2. How many atoms of Neon if I have 121L of this element @STP?<br> 3. What is mass (in kg) do I have to weigh out to get 9.21E24 molecules of Heptasulfur tribromide?<br> 4. How many formula units of Tin (IV) sulfate do I have if I have 79.2g of this compound?<br> 5. What is volume (in L) of 5.05E24 atoms of Helium gas (@STP).<br> ---<br> 6. How many kg of Carbon monoxide gas do I have if there are 16.4 L @STP of this gas<br> 7. What is the mass of 3.06E20 formula units of Aluminum carbonate?<br> 8. What is the volume of 2.8E24 molecules of hydrogen gas?<br> 9. How many grams are there in 6.45E25 molecules of S<sub>3</sub>Cl<sub>4</sub>?<br> 10. How many f.u. in 2.00kg of potassium sulfate?<br> <br>
