Silver Nitrate Day Four Lab

OBJECTIVE

• 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
• AgNO₃ = 169.872 g/mol
• Cu(NO₃)₂ = 187.554 g/mol

DATA

8. mass of Beaker B with Cu(NO₃)₂ = g

PROCEDURE

1. Mass out Beaker B with the Cu(NO₃)₂.
2. Wash the Cu(NO₃)₂ down the drain with plenty of water.
3. Scrub Beaker B clean with soapy water.
4. Enter data into computer.

CALCULATIONS (on back of lab paper, numbered)

1. actual mass of Cu(NO₃)₂ = g
2. theoretical mass of Cu(NO₃)₂ = g
3. percent yield of Cu(NO₃)₂ = %
