0.0034L
Explanation:
Given parameters:
Number of molecules of oxygen gas = 9.23 x 10¹⁹molecules
Unknown:
Volume of oxygen = ?
Solution:
Assuming the gas is at standard temperature and pressure conditions;
Volume of gas = number of moles x 22.4
we need to find the number of moles of the oxygen gas;
number of moles = }[/tex]
Number of moles = }{6.02 x 10
}[/tex]
Number of moles = 1.53 x 10⁻⁴moles
Volume of gas = 1.53 x 10⁻⁴ x 22.4 = 0.0034L

To solve for absolute pressure, you will need this formula:
Where:
= absolute pressure
= atmospheric pressure
r (rho) = density
g = acceleration due to gravity constant
h = depth (in this case)
rgh is the formula for pressure of fluids
So with your given, we just need to insert it into the formula:
= 1.01 x 
x (1,025 
x 9.8 
x 15 m
= 1.01 x + 150,675
= 1.01 x + 1.51 x
= 2.52 x 
This is your absolute pressure.
