How Do You Calculate Moles Of Oxygen?
Oxygen is a prevalent gas in the Earth’s atmosphere that is essential for living organisms. Chemically, this gas consists of two oxygen atoms denoted with the formula “O2.” The quantity of the oxygen gas can be measured in moles that serve as a specific unit in chemistry to express the amount of substance. You can straightforwardly compute moles if the mass of an oxygen sample is known. The other method relies on the ideal gas law that allows you to calculate oxygen moles if the volume of the gas under certain pressure/temperature conditions is given. Get familiar with the ideal gas law expressed using the following formula: PV = nRT; “P” is pressure, “V” is volume, n is the number of moles of a gas, “R” is the molar gas constant and “T” is temperature. Record the molar gas constant “R” that is necessary for this calculation: R= 8.314472 J/mole x K (see the Resources section). Note that the constant is given in the International System of Units (SI) and, hence, other parameters in the
