Given parameters:

Percentage by mass of Nitrogen in fertilizer = 19%

Mass of fertilizer = 10.0oz

Unkown:

Mass in grams of Nitrogen in the container = ?

Solution

To solve this problem, we first find the percentage of mass of nitrogen in the fertilizer by a taking a percentage of the given mass of the fertlilizer:

Mass of Nitrogen in ounces of the fertilizer =

                                             [tex]\frac{19}{100}[/tex] x 10 = 1.9oz

Since we are expected to express this in grams:

         1oz = 28.35g

         1.9oz = 1.9 x 28.35, 53.87g
