Answer:
The weight of ammonium phosphate is 10 gm
Explanation:
The chemical reaction of ammonium phosphate formation is as follows.
![3NH_{3}+H_{3}PO_{4} \rightarrow [(NH_{4})_{3}PO_{4}]](https://tex.z-dn.net/?f=3NH_%7B3%7D%2BH_%7B3%7DPO_%7B4%7D%20%5Crightarrow%20%5B%28NH_%7B4%7D%29_%7B3%7DPO_%7B4%7D%5D)
From the reaction one mole of phosphoric acid is equivalent to the one mole of ammonium phosphate.
So, "n" mole of phosphoric acid is equivalent to the "n" mole of ammonium phosphate.
Number of moles in 7.1 grams of phosphoric acid = 
<u>Formation weight of ammonium phosphate :</u>
Weight of ammonium phosphate = 
Round the answer to 2 significant digits
Weight of ammonium phosphate = 10 gm
Cells are considered the basic units of life in part because they come in discrete and easily recognizable packages. That's because all cells are surrounded by a structure called the cell membrane — which, much like the walls of a house, serves as a clear boundary between the cell's internal and external environments. The cell membrane is sometimes also referred to as the plasma membrane.
Cell membranes are based on a framework of fat-based molecules called phospholipids, which physically prevent water-loving, or hydrophilic, substances from entering or escaping the cell. These membranes are also studded with proteins that serve various functions. Some of these proteins act as gatekeepers, determining what substances can and cannot cross the membrane. Others function as markers, identifying the cell as part of the same organism or as foreign. Still others work like fasteners, binding cells together so they can function as a unit. Yet other membrane proteins serve as communicators, sending and receiving signals from neighboring cells and the environment — whether friendly or alarming
Cell A is very large and has many organelles, while cell B is very small and has only a few organelles.
