First, find the number of moles of UF6
Avagadro's number = 6.023 x 10^23
Number of moles = 8.0 x 10^26 / Avagadro's number = 8.0 x 10^26 / 6.023 x 10^23 = 1.328 x 10³ moles
Molecular weight of UF6 = Molecular weight of U (238.02891) + Molecular weight of F6 (6 x 18.9984032) = 238.02891 + 113.9904192 = 352.0193292 g/mol
Therefore mass of 8.0 x 10^26 UF6 molecules = 352.0193292 g/mol x 1.328 x 10³ moles = 467.481669 x 10³ grams
        
             
        
        
        
Answer:
Explanation: E. 12 because it has the highest acidity rate.
 
        
             
        
        
        
First convert volume to mass:
mass = 0.789 g/mL * 155 mL = 122.295 g
 
Then convert mass to number of moles:
number of moles = 122.295 g * (1 mole / 46 g) = 2.66 moles
 
Using avogadros number, we get the molecules:
<span>number of molecules = 2.66 moles * 6.022 x 10^23 molecules
/ mole = 1.6 x 10^24 molecules</span>
 
        
             
        
        
        
A map that shows the location of volcanoes is called a Geologic Map. This kind of map contains information about the geological history and condition of volcanic sites.
<h3>
What do Geologic Maps indicate?</h3>
Geologic maps indicate the following:
- the location of volcanos
- age of rock deposits found near the volcano
- which volcanoes are active and those that aren't
- types of rocks at these sites
- faults fracture etc.
Note that the map specific to the question is unavailable hence the general response.

Answer:

Explanation:
Force can be found by multiplying the mass and the acceleration. 

The mass of the sled is 300 kilograms and the acceleration is 2 meters per second squared.

Multiply.

1 kilogram-meter per second squared is equal to 1 Newton. Therefore, 600 kilograms-meter per second squared is equal to 600 Newtons. 

The force used on the sled is 600 Newtons.
