Aplant fertilizer contains 19 % nitrogen (n) by mass. in a container of soluble plant food, there are 10.0 oz of fertilizer. how many
grams of nitrogen are in the container?

53.87g

Explanation:

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 =

                                              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

a rain shadow is a dry region of land on the side that is protected against the prevailing winds of a mountain range. the prevailing winds are the winds that occur most of the time in a particular place of the earth

prevailing winds carry air toward the mountain range. as the air rises up over a mountain range, the air cools, water vapor condenses, and clouds form. on this side of the mountains, called the windward side, precipitation falls in the form of  rain  or snow. this dry air produces a  rain shadow.

answer: -

reaction:

na + cl ⇌ nacl

balanced chemical equation:

na + 2cl ⇌ nacl2

sodium + clorine goes to form sodium chloride (table salt).

the product is nacl2.

and the reactants are na and cl.

⇌(double head arrow) means reversible reaction).
