Answer:
1223.38 mmHg
Explanation:
Using ideal gas equation as:

where,  
P is the pressure
V is the volume
n is the number of moles
T is the temperature  
R is Gas constant having value = 
Also,  
Moles = mass (m) / Molar mass (M)
Density (d)  = Mass (m) / Volume (V)
So, the ideal gas equation can be written as:

Given that:- 
d = 1.80 g/L
Temperature = 32 °C
The conversion of T( °C) to T(K) is shown below:
T(K) = T( °C) + 273.15  
So,  
T = (32 + 273.15) K = 305.15 K 
Molar mass of nitrogen gas = 28 g/mol
Applying the equation as:
P × 28 g/mol  = 1.80 g/L × 62.3637 L.mmHg/K.mol × 305.15 K 
⇒P = 1223.38 mmHg
<u>1223.38 mmHg must be the pressure of the nitrogen gas.</u>
 
        
             
        
        
        
Answer:
This is an example of a food chain
Explanation:
Think of it as a chain reaction. The grass feeds and nourishes the prairie dog. Upon eating the prairie dog, the coyote gets the nutrients from both the grass the prairie dog ate and from the prairie dog itself.
