Oxygen in air by weight
WebThere is a well-known p V = m M R T universal gas formula. Here: p is the pressure. V is the volume. m is the mass. M is the molar mass of the gas. R is the universal gas constant ( 8.314) T is the absolute temperature (in Kelvin) Although your question literally interpreted asks for the weight of the gas, from the context it is clearly visible ... WebCalculate the mass of oxygen, which consists of 2 moles, each mol made up from 2 atoms of oxygen. \[m_o =2 \cdot 15.999 \cdot 2= 63.996 \text{ g}\] Step 6. Calculate the necessary mass of air which contains the calculated mass of oxygen, taking into account that air contains around 21 % oxygen.
