Ammonium phosphate ((NH4)3PO4) is an important ingredient in many fertilizers. It can be made by reacting phosphoric acid (H3PO4) with ammonia (NH3).
What mass of ammonium phosphate is produced by the reaction of 4.9 g phosphoric acid?

7.46 g

Explanation:

Equation for the reaction can be represented as:

1 mole of phosphoric acid is equivalent to 1 mole of ammonium phosphate in the above reaction; and as such;

numbers of moles of phosphoric acid = numbers of moles of ammonium phosphate

Given that the mass of phosphoric acid = 4.9 g; we can determine the number of moles of phosphoric acid in the process.

mass = 4.9 g

molar mass = 98 g/mol

numbers of moles =

= 0.05 mole

Therefore, the mass of ammonium phosphate can be determine:

mass = number of moles × molar mass

mass of  ammonium phosphate = 0.05 mole  ×  149.09 g/mol

mass of  ammonium phosphate = 7.4545 g

mass of  ammonium phosphate ≅ 7.46 g

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.
