Question

Сколько кубических метров кислорода может быть получен путем фракционной перегонкой жидкого воздуха если исходный объем воздуха был равен 800 метров в кубе а как известно объемная доля кислорода в воздухе составляет 0.21

Answer 1

Решение.
V(O₂)=Vвозд*φ(О₂)
V(O₂)=800м³*0,21=168м³
Ответ. V(O₂)=168м³

Answer 2

Calculation of the Volume of Oxygen Obtained through Fractional Distillation of Liquid Air

To calculate the volume of oxygen obtained through fractional distillation of liquid air, we need to consider the initial volume of air and the volumetric fraction of oxygen in air.

Given: - Initial volume of air = 800 cubic meters - Volumetric fraction of oxygen in air = 0.21

To find the volume of oxygen obtained, we can multiply the initial volume of air by the volumetric fraction of oxygen:

Volume of oxygen obtained = Initial volume of air * Volumetric fraction of oxygen

Substituting the given values:

Volume of oxygen obtained = 800 cubic meters * 0.21

Calculating the result:

Volume of oxygen obtained = 168 cubic meters

Therefore, through fractional distillation of liquid air, it is possible to obtain 168 cubic meters of oxygen.
