Pick an element from the Periodic Table AFTER number 25, Mn, and do not pick a diatomic element. Pick something different and fun! Now answer the following questions on a piece of paper which you will upload as a pdf file, and show all your work with units for calculations for any credit. Use your CHM 130 Periodic Table for molar masses and use 6.02 x 1023 for Avogadro's number or you may be counted wrong!!! 1. What is the symbol for your element? (Must be after Mn in Periodic Table) 2. What is the molar mass of your element? (include units) 3. How many atoms are in a mole of your element? (No calculation needed) 4. If you had 14.5 grams of your element, how many moles is that?

4. If you had 14.5 grams of your element, how many moles is that?
5. If you had 14.5 grams of your element, how many atoms is that?
6. Theoretically speaking, if your element was in the gas state at STP, how many grams is 2.25 liters of your element? (Most elements are not gases at STP so this question is just theoretical) You may not use the
