Presentation transcript:

Grab binders, handouts, returned work & calculators, begin the Do Now 5/22 DO NOW 1. Out of the following topics, list the top 3 you struggle with the most - Calculating Molar Mass - Balancing Reactions - Converting from Mass to Moles - Converting from Moles to Mass - Identifying the Molar Ratio - Converting between Moles X and Moles Y - Climbing the Mole Hill 2. Calculate the Molar Masses for the following compounds: a. H 3 PO 4 b. NaOHc. Ag(SO) 2

Stoichiometry Recap Molar Mass = sum of mass #’s of all elements in a compound (g/mol) Mass  Moles = grams ÷ Molar Mass Mole X  Mole Y = use Molar Ratio Moles  Mass = moles x Molar Mass

Stoichiometry Debrief Conversion Factors: Molar Mass Molar Ratio Keep track of your UNITS & COMPOUNDS!

Quiz 3 Review Stations Protocol Directions: -Show ALL of your work. Use a separate sheet of paper if needed -8 min at each station -No more than 5 people at a station -MUST complete at least 3 stations as today’s Exit Ticket -3 unfinished stations = HW

Exit Ticket 6 Directions: You have 10 minutes to complete the Exit Ticket to the best of your ability. You MAY NOT use notes, but you may use a Periodic Table. When finished submit to the class bucket.

Grab binders, handouts, returned work & calculators, begin the Do Now 5/23 DO NOW 1. Take 5 min to study for today’s quiz on Molar Mass, Balancing Reactions, & Stoichiometry. 2. Set out your Periodic Table, a calculator, and a separate sheet of paper on your desk. Clear your desk of all other materials.

Quiz 3 30 min to complete (we will track immediately after) DO NOT write on the quiz, write answers on separate sheet of paper When finished turn in the quiz upfront, grab a colored pencil & calculator, and sit silently. – Things to Do: HW 5 Lab 2: Biodegradable Soap Lab Report Lab 3: Aspirin Lab or Lab 4: Bioplastics Lab Other course work
