Stoich Review

Particles in 10.5 mols of Ammonium Nitrate

1.25 x atoms of magnesium into Mols

6.5 x particles of potassium chloride into mols

9.99 mols of Sodium hydroxide into particles

Mols are in 10 grams NH 4 CN

Grams of 0.75 mols ZnSO 4

0.5 mols Mg(CN) 2 into grams

Mass of 0.2 mols Rb 2 CO 3

32 g K 2 Te into Mols

Mass of 1.1 mols CuBr 2

How many grams are there in 3.4 x molecules of NH 3

____ NaCl + _____ F 2  ____ NaF + _____ Cl 2 Calculate the number of mols of NaF produced by 5.25 mols of Fluroine?

____ NaCl + _____ F 2  ____ NaF + _____ Cl 2 How many mols of Chlorine is produced if we have 25 mols of Fluorine?

____ AgNO 3 +____ Cu  _____ Cu(NO 3 ) 2 + _____Ag How many mols of silver are produced if 5.5 mols of copper was used in the beginning?

____ AgNO 3 +____ Cu  _____ Cu(NO 3 ) 2 + _____Ag If we started with 5.5 grams of Cu, how many mols of Ag was produced?

____ AgNO 3 +____ Cu  _____ Cu(NO 3 ) 2 + _____Ag If grams of Copper (II) Nitrate was produced, how many mols of Cu was used in the beginning?

____ AgNO 3 +____ Cu  _____ Cu(NO 3 ) 2 + _____Ag If we started with 15 grams of AgNO 3, what mass (in grams) of Ag was produced?

C 2 H O 2  2 CO H 2 O If you start with 45 grams of ethylene (C 2 H 4 ), how many grams of carbon dioxide will be produced?

2 HCl + Na 2 SO 4  2 NaCl + H 2 SO 4 If you start with 20 grams of hydrochloric acid, how many grams of sulfuric acid will be produced?

___CuCl 2 + ___NaNO 3  ___Cu(NO 3 ) 2 + ___NaCl If 25 grams of copper (II) chloride react with 21 grams of sodium nitrate, how much sodium chloride can be formed?

___CuCl 2 + ___NaNO 3  ___Cu(NO 3 ) 2 + ___NaCl What is the LR? What is the ER?

___CuCl 2 + ___NaNO 3  ___Cu(NO 3 ) 2 + ___NaCl How much ER is left after the reaction drives to completion?

___CuCl 2 + ___NaNO 3  ___Cu(NO 3 ) 2 + ___NaCl How many grams of copper(II) nitrate is formed?

What to expect on Assessment: 1.Avogadros Number 2.Molar Mass (Mol-Mass and reverse) 3.Mol-Mol (balance equation) 4.Mass-Mass (combo of all the above) 5.LR/ER (view notes from Friday, very similar, 1 st and 3 rd Period ONLY)
