Consider the chemical equation for the production of water: 2 H2+O2→2 H2O. If 100 grams of oxygen gas are used, what would the percent yield be if 75 g of H2O was produced? Show your work.

The percentage yield of water is 66.67%.

Explanation:

Mass of oxygen gas = 100 g

Moles of oxygen gas =

According to reaction, 1 mole of oxygen gives 2 moles of water, then 3.125 moles of oxygen will give:

Mass of 6.25 moles of water :

6.25 mol × 18 g/mol = 112.5 g

Theoretical yield of water = 112.5 g

Experimental yield of water = 75 g

Percentage yield :

The percentage yield of water is 66.67%.

plants need sunlight, water, and carbon dioxide to make food. plants use the raw materials of water, nutrients they absorb from soil, and carbon dioxide to make sugars the plant can use. energy from the sun and chlorophyll are also needed.
