Answer:

2. It is the simplest ratio of atoms in a formula unit.

Explanation:

The empirical formula refers to how to provide the minimum proportion in which chemical elements combine into one substance. Sometimes it may happen that the minimum formula is equal to the molecular formula of the compound; However, this is not always true.  In short, the empirical formula refers to the simplest ratio of atoms in a unit of formula.

For example, the empirical or minimal formula of water is H2O, indicating that there is a 2: 1 ratio between the elements that make up water molecules. And, coincidentally, this is also the molecular formula of water.

When you are done using the glassware from a kit, what should you do?
lakkis [162]

Answer:

A. Wipe down the glassware to remove any cleaning solvent.

Explanation:

· Remove stoppers and stopcocks when they are not in use. Otherwise, they may "freeze" in place. You can de-grease ground glass joints by wiping them with a lint-free towel soaked with ether or acetone. Wear gloves and avoid breathing the fumes. The deionized water rinse should form a smooth sheet when poured through clean glassware.

How many molecules are there in 8.25 moles of CaHia?
expeople1 [14]

The number of molecules : 4.967 x 10²⁴

<h3>Further explanation   </h3>

A mole is a number of particles(atoms, molecules, ions)  in a substance

This refers to the atomic total of the 12 gr C-12  which is equal to 6.02.10²³, so 1 mole = 6.02.10²³ particles  

Can be formulated :

N = n x No

N = number of particles

n = mol

No = 6.02.10²³ = Avogadro's number

8.25 moles of C₈H₁₈

The number of molecules :

\tt 8.25\times 6.02\times 10^{23}=4.967\times 10^{24}
