Answer:
A) 4.3 × 10²⁴ atoms
Explanation:
Step 1: Given data
Moles of neon: 7.2 moles
Step 2: Calculate the number of atoms present in 7.2 moles of neon
In order to convert moles to toms, we need a conversion factor. In this case, we will use Avogadro's number: there are 6.02 × 10²³ neon atoms in 1 mole of neon atoms.
7.2 mol × 6.02 × 10²³ atoms/mol = 4.3 × 10²⁴ atoms

Division (asexual) method, and the sexual method of reproduction where two organisms produce an offspring. The sexual reproduction requires the interaction of two organisms; gametes, typically a fertilization. The offspring consists of characteristics derived from both of the parental organisms.
Answer:
325mg of Aspririn
Explanation:
First you should note the information that the problem gives you:
- The bottle of Aspirin has 5gr (grains)
- 1gr(grain) = 65mg (miligrams)
Also, the problem is asking about how many aspirin are in 5 gr (grains), so you should use a conversion factor, as follows:
-First you should put the quantity you need to convert:

-Then you write the denominator of the conversion factor that must have the same units that you want to convert, in this case gr:

-Then you write the numerator with the units that you want to obtain and the numerical equivalence between the units, in this case:

-Finally you multiply numerators and divide by denominators:
