Answer 1

Approximately 55.59 grams

Step-by-step explanation:

To find the number of grams of nitrogen in the container, you can calculate 14% of the total mass of the fertilizer in ounces and then convert it to grams.

1. Calculate the mass of nitrogen in ounces:

Mass of nitrogen (oz) = 14% of 14.0 oz = 0.14 * 14.0 oz = 1.96 oz

2. Convert the mass of nitrogen from ounces to grams. There are approximately 28.3495 grams in 1 ounce:

Mass of nitrogen (grams) = 1.96 oz * 28.3495 g/oz ≈ 55.59 grams

So, there are approximately **55.59 grams** of nitrogen in the container.
