10.2. Mass, Volume, and the Mole http://www.ck12.org
- What is the mass (in grams) of 3.2 moles of glucose (C 6 H 12 O 6 )?
- You are running an experiment that needs three moles of NaHCO 3 , and you only have 150 grams of material.
Calculate the number of moles you have, and determine if this is enough to run the experiment. - A balloon contains 96 grams of CO 2 gas at STP. How many moles are present?
- How many atoms are there in 12.2 grams of Zn?
- A container holds 68.5 liters of HBr gas. What is the mass of HBr in the container?
