1.The dissolved oxygen concentration in a sample of
freshwater at 15 C is measured at
13 mg/L What is the oxygen volume (mL) contained in a 1 liter
sample at 1 atmosphere?
*Hint use the ideal gas law P V =n•R•Twhere P is
absolute pressure in atmosphere, V is
volume in liters, n is number of moles, R is the gas constant for
Oxygen (R= 0.082
L-atm-K-mol), T is absolute temperature in degrees Kelvin (K="C
+273.15), and the molecular
weight of Orygen (02) is 32 grams/mol.

Language: Python The ideal gas law is a mathematical approximation of the behavior of gasses as pressure, volume, and temperature change. It is usually stated as: PV = nRT where P is the pressure in pascals, V is the volume in liters, n is the amount of substance in moles, R is the ideal gas content, equal to 8.314 (J/mol K), and T is the temperature in degrees kelvin. Write a program that computes the amount of gas in moles...
