Part III

Print out One Step/two Step graphic organizer ([CP One Two Step Mole Calculation Graphic Organizer with Work Space]) and fill out form to get correct answer for the following problems.

1. How many liter @STP of elemental nitrogen gas (N₂ if I have 85.2g of this gas?

2. How many grams of Mg₁Br₂ do I have if I mass out 6.28 moles of this ionic compound?

Part IV

Print out Stoichiometry graphic organizer ([CP Stoichiometry Graphic Organizer with Work Space]), fill in and answer correctly.

1) Using the balanced equation from question 1 in Part II above, how many grams of calcium bromide do I need to react to obtain 56.4grams of sodium bromide?

2) Using the balanced equation from question 3 in Part II above, how many molecules of dihydrogen monoxide do I produce if I react 65.2grams of elemental oxygen (remember it is a diatomic element).
