Answer:
The sum of the molar masses of each isotope of the element.
 
        
                    
             
        
        
        
Density is the mass of compound divided by its volume can be shown as follows:


40 mL of snow having 20 g of mass calculated from density.
Now, 10 cm of snow = 3.93 inches = 20 g  
As, 10 inches of rain will produce 11 inches of ice as the volume of ice is bigger than rain water.
10 inches rain = 11 inches snow
3.93 inches of snow produced by  

Thus, 3.57 incehs of rain produces by 10 cm snow.
 
        
             
        
        
        
Wouldn't you take Avogadro' number and multiply by 3.80 maybe
        
             
        
        
        
Explanation:
It is given that,
The time period of artificial satellite in a circular orbit of radius R is T. The relation between the time period and the radius is given by :

The radius of the orbit in which time period is 8T is R'. So, the relation is given by :

 
  


So, the radius of the orbit in which time period is 8T is 4R. Hence, this is the required solution.   
 
        
             
        
        
        
Answer:
E and B
Explanation:
the warmer the weather the faster it will decompose, this why is why sometimes bodies last longer frozen, or in cool temperatures. 
that statement takes a out.
An illness shouldn't effect a decomposing body
Weight also shouldn't effect a decomposing body
Being buried can make bodies decompose fast because of all the bugs and other animals that will get down there and decompose it faster
Answer: B,E
