<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. What is the mass of 0.015 mole of calcium oxide?<br> 2. How many molecules in 1.12g of carbon dioxide?<br> 3. What is the volume of 0.10 mole of neon gas?<br> 4. What is the number of molecules in 2.5 L of helium gas?<br> 5. What is the mass of 6.67 L of argon gas?<br> 6. How many formula units are in 25g of <nowiki>NaOH</nowiki><br> 7. What is the mass of 2.3E21 molecules of <nowiki>SiH</nowiki><sub>4</sub>?<br> 8. What is the volume of 4.5E24 molecules of hydrogen gas?<br> 9. How many grams are there in 5.45E24 f.u. <nowiki>BaCl</nowiki><sub>2</sub>?<br> 10. How many f.u. in 1.00kg of calcium nitrate?<br> <br>
