  1. Entry Task: Feb 1st Friday WRITE THE QUESTION DOWN Entry Task Question: How many grams are there in 0.25 moles of Magnesium nitrate? You have 5 minutes!

  2. Agenda: • Discuss Mole/Mass conversion ws • Mole Lab • H.W. Mole lab post questions/calculations

  3. Moles to grams conversion O2 O= 15.999 g X 2 = 31.998 g 1 mole = 31.998 grams 6.38 mol of O2 Place starting amount here 6.38 mole O2 ---------- 31.998 grams of O2 = 204.1 grams of O2 -------------- 1 mole O2 Place conversion here = 2.04 X 102 grams of O2

  4. Moles to grams conversion Al 1 mole = 26.98 grams 4.00 mol of Al Place starting amount here 4.00 mole Al ---------- 26.98 grams of Al = 108 grams of Al -------------- 1 mole Al Place conversion here = 1.08 X102 grams of Al

  5. Moles to grams conversion Fe(NO3)3 Fe= 55.845 g X 1 = 55.845 g 0.250 moles iron III nitrate N= 14.0067 g X 3 = 42.02 g O= 15.999 g X 9 = 143.99 g Place starting amount here 1 mole = 241.85 grams 0.250 mole Fe(NO3)3 241.85 grams of Fe(NO3)3 --------------- = 60.46 grams of Fe(NO3)3 1 mole Fe(NO3)3 -------------- Place conversion here = 6.05 x101 grams of Fe(NO3)3

  6. Moles to grams conversion Cu2 SO3 Cu= 63.546 g X 2 = 127.09 g 3.00 moles Copper I sulfite S= 32.065 g X 1 = 32.065 g O= 15.999 g X 3 = 47.997 g Place starting amount here 1 mole = 207.152 grams 3.00 mole Cu2SO3 207.152 grams of Cu2SO3 --------------- = 621.4 grams of Cu2SO3 1 mole Cu2SO3 -------------- Place conversion here = 6.21 x102 grams of Cu2SO3

  7. Grams to moles conversions Zn 188 g Zn Zn= 65.409 g X 1 = 65.409 g 1 mole = 65.409 grams Place starting amount here Place conversion here -------- 188 g of Zn 1 mole of Zn = 2.874 moles of Zn --------- 65.409 g of Zn = 2.87 moles of Zn

  8. Grams to moles conversions 161 g Br2 Br= 79.904 g X 2 = 159.808 g 1 mole = 159.808 grams Place starting amount here Place conversion here -------- 161 g of Br2 1 mole of Br2 = 1.00 moles of Br2 --------- 159.808 g of Br2 = 1.00 moles of Br2

  9. Grams to moles conversions (NH4)2SO4 5.00 g Ammonium sulfate N= 14.007 g X 2 = 28.014 g H= 1.0079 g X 8 = 8.06 g S= 32.065 g X 1 = 32.065 g Place starting amount here O= 15.999 g X 4 = 63.996 g 1 mole = 132.135 grams ---------- 5.00 g of (NH4)2SO4 1 mole of (NH4)2SO4 = 0.03784mole of (NH4)2SO4 ----------- 132.135 g of (NH4)2SO4 = 3.78 x 10-2 mole of (NH4)2SO4

  10. Grams to moles conversions K2CO3 88.0 g potassium carbonate K= 39.098 g X 2 = 78.196 g C= 12.01 g X 1 = 12.01 g O= 15.999 g X 3 = 47.997 g Place starting amount here 1 mole = 138.2 grams ---------- 88.0 g of K2CO3 1 mole of K2CO3 = 0.63675mole of K2CO3 ----------- 138.2 g of K2CO3 = 6.37 x 10-1 mole of K2CO3
