Silver Nitrate Day Three Lab

OBJECTIVE

• Use stoichiometry to predict the mass of a product
• and calculate percent yield.

INFO

• Cu + 2AgNO₃ --> 2Ag + Cu(NO₃)₂
• Cu = 63.546 g/mol
• Ag = 107.868 g/mol
• N = 14.007 g/mol
• O = 15.999 g/mol

DATA

7. mass of Beaker A with Ag = g

PROCEDURE

1. Mass out Beaker A with the Ag.
2. Return Beaker A to the fume hood.
3. Move Beaker B to the white paper on the counter.
4. Enter data into computer (silver_nitrate_3)

*** SECOND DAY ***

5. Pour 10 mL of 6M HNO₃ into Beaker A with the Ag.
• teacher will help with this

CALCULATIONS (on back of lab paper, numbered)

1. actual mass of Ag = g
2. theoretical mass of Ag = g
3. percent yield of Ag = g
