We are given that:

1 atom N = 3 atom of the metal

1 mol N = 3 mol of the metal

 

First let us convert the given nitrogen into number of moles:

moles N = 1 g / (14 g / mol)

moles N = 0.071 mol

 

Therefore the atomic or molar mass of the metal is:

molar mass = 1.486 g / (3 * 0.071 mol)

<span>molar mass = 6.93 g / mol</span>

ddd [48]

Answer:

Following are the solution to these question:

Explanation:

Simple diffusion implies which molecules can move across a cell membrane instead of using the incorporated protein structure channels. Its flow of molecules across these canals is enabled by diffusion. It has steroid hormones and N2.

Facilitated diffusion of molecules via cell membranes, or active transportation, which would be the random mass transit process of molecules or ions via unique cellular membranes from the transmembrane. It has K+ and Glucose.

Max Points! help me!<br>True or False? Electrons are larger than molecules.
Darya [45]

False because electrons are what help make up molecules, therefore they have to be smaller.
