Answer:

the correct expression is 125.4 g ZnCO3 * 1 mol ZnCO3/6.022x10^23 formula units ZnCO3

Explanation:

The conversion factor that correctly expresses the relationship between the molar mass and the number of formula units of the compound is as follows.

Avogadro's number is defined as 6.022x10^23 particles/mole, therefore the conversion would be equal to:

125.4 g ZnCO3 * 1 mol ZnCO3/6.022x10^23 formula units ZnCO3

Answer : ZnCO_{3} will be 1 mole of ZnCO_{3} / 125. 40 g of ZnCO_{3}

Explanation : The molar mass and the formula units are the same thing in any compound so when given a molar mass of compound then one mole of that compound is divided by its molar mass. Where one mole will be equal to avogadro's number which is 6.022 X 10^{23}.

write down the way you had to behave to illustrate the behavior of particles as a gas condenses to form a liquid
Rainbow [258]

Gases near together and vibrate in position however, don't circulate beyond each other. In a liquid, the particles are interested in every different but now not as a great deal as they may be in a strong.

The particles of a liquid are near together, constantly transferring, and may slide beyond one another. The Kinetic-molecular concept attempts to explain the behavior of fuel molecules based totally on the nature of gasoline. The principle is grounded on  simple assumptions

In gases the debris passes swiftly in all directions, regularly colliding with every different facet of the box. With a boom in temperature, the debris gains kinetic strength and passes more quickly. Gasoline is a state of matter that has no constant form and no fixed extent. Gases have a decreased density than other states of the count, together with solids and liquids. there may be a high-quality deal of empty area between debris, that have loads of kinetic energy and aren't especially drawn to one another.
