1. How many grams of zinc metal will react completely with 5. 4 L of 2
How many grams of zinc metal will react completely with 5.4 L of 2.8 M HCl? Show all of the work needed to solve this problem.
Zn (s) + 2 HCl (aq)  ZnCl2 (aq) + H2 (g)
1 mol Zn is to 2 mol HCl from balanced chemical equation
1 mol Zn is to 65.4 g Zn (mass on periodic table)

2. Describe, in detail, how to make 3. 0 liters of a 0
Describe, in detail, how to make 3.0 liters of a 0.98 molar HCl solution from a 10.5 molar HCl stock solution.
M1V1= M2V2
0.98 M x 3.0 L = 10.5 M x V2
2.94 mol / 10.5 mol / L = L solution

3. How many grams of a stock solution that is 85
How many grams of a stock solution that is 85.5% H2SO4 by mass would be needed to make grams of a 45.0% by mass solution? Show all of the work needed to solve this problem.

4. 2 Al (s) + 3 Fe(NO3)2 (aq)  3 Fe (s) + 2 Al(NO3)2 (aq)
How many grams of iron metal do you expect to be produced when 305 grams of a 75.5% by mass iron (II) nitrate solution reacts with excess aluminum metal? Show all of the work needed to solve this problem.
2 Al (s) + 3 Fe(NO3)2 (aq)  3 Fe (s) + 2 Al(NO3)2 (aq)
305 g Fe(NO3)2 x .755 = 230 g Fe(NO3)2
you need to find moles of iron to find grams of iron by using mol/mol ratio in equation
230 g Fe(NO3)2 x
