  1. March 8, 2012 AGENDA: 1 – Bell Ringer & Part. Log 2 – Review Homework 3 – CN: Gram to Mole Conversion 4 – Weekly Raffle! 5 – Work Time Today’s Goal: Students will be able to convert from grams to moles. Homework • Mole and Mass Conversions (full sheet) • Mixed Mole-Mass Conversions (half sheet) • Study for tomorrow’s QUIZ! • Tomorrow is the Last Day to turn in Last Week’s Work

  2. Cornell Notes • Topic: Gram to Mole Conversion • Date: 3/8/2012 • Remember: We use molar mass for all of this week’s conversions. • Yesterday  mole to gram conversions • Example: If you have an 8.0 mole sample of NaCl, how many gramsdo you have? 1. NaCl= Na = Cl = 58.44 g 1 mol 2. 8.0 mole NaClx 58.44 g 1 mol = 467.52 g NaCl • = 22.99 1x • 22.99 = 35.45 1x +______ 35.45

  3. Cornell Notes (continued) • What if you were given a200 gsample of NaCl, and you wanted to convert to moles? Molar Mass of NaCl = 200 g mole  gram gram  mole multiplication division • 58.44 g • 1 mole • 1 mole • 58.44 g • = • x 1 mole= • 58.44 g 200 mole = 58.44 3.42 mol NaCl

  4. Cornell Notes (continued) • Example: • If you have a 150 gsample of AlPO4, how many moles do you have? 1. AlPO4= Al = P = O = 121 g mol 2. 150 gx 1 mol 121 g = 1.24 mol AlPO4 • = 26 1 x • 26 1 x 31 = 31 • = 64 + 4 x • 16
