Lead nitrate can be decomposed by heating. what is the percent yield of the decomposition reaction if 9.9 g of pb(no3)2 are heated to give 5.5 g of pbo? 2pb(no3)2(s) → 2pbo(s) + 4no2(
g. + o2(
g.

Percentage yield is 82.44%

Explanation:

Percentage yield is the ratio of actual product produced to theoretical product produced.

Step 1: Determine the actual yield of the reaction

The number of moles of are determined using the below formula where 'n' is the number of moles, 'm' is the mass and 'M' is the molar mass

The number of moles of give the actual yield of the reaction

Step 2: Determine the theoretical yield of the reaction

The same formula for number of moles is used to determine the moles of

Based on the balanced chemical equation given in the question, one mole of should be produced for every mole of decomposed. Thus,

Step 3: Determine percentage yield
