Answer:
d. 0.433 atm
Step-by-step explanation:
Pascal and atmosphere are both units of pressure.
The expression for the conversion of pressure in Pascal to pressure in atm is shown below:
P (Pa) = 
 P (atm)
 P (atm)
Given the value of pressure = 43,836 Pa
So, 
43,836 Pa = 
 atm
 atm
Pressure = 0.433 atm
Hence, option d. 0.433 atm is correct.
