Pressure of the Mixture = 101.4 kpa
Pressure of the helium phe = 82.5 kpa
Pressure of CO2 pco2 = 0.4 kpa.
Partial pressure of oxygen = Pressure of the Mixutre - (Pressure of the
helium + Pressure of CO2)
Partial pressure of oxygen = 101.4 - 82.5 - 0.4
Partial pressure of oxygen = 18.5 kPa

The answer is C.) equal to. When balancing chemical equations, its important to make sure each coefficient is accurate to each element to ensure that the mass of the reactants and products are equal.
In chemistry, the molar mass of a chemical compound is defined as the mass of a sample of that compound divided by the amount of substance in that sample, measured in moles. It is the mass of 1 mole of the substance or 6.022×10²³ particles, expressed in grams.
