EEEB 7. Air is a source of reactants for many chemical reactions. A sample of dry air of total mass 1.00g consists almost entirely of 0.76g of nitrogen gas and 0.24g of oxygen Calculate the partial pressures of each of these gases when the total pressure is 0.87atm. PTOTAL = PA + PB + P₂ N₂ = 0.769 0₂ 0.24g PrOTAL = 0.87atm 8. The box below contains a visualized mixture of gas A (represented by the black circles) and gas B (represented by the white circles) If the partial pressure of gas A is 422 Torr, determine Pr in the box, in Torr. Hint: it will help to imagine each circle represents one mol of each species.

Mole Concept

Mole concept is a method to determine the amount of any substance that consists of some elemental particles using a grouping unit called ‘mole’. The mole concept enables one to handle the large amount of small elementary particles. The mole concept can be used in many calculations related to mole calculation, molar amount, mole ratio, and so on, which are significant in chemistry.
