Question

Вычислите объем кислорода (н.у) количеством пешестви 2,5 моль. Уметь применять закон Авогадро для расчета объема гази при (н.у). (4 балла)

Answer 1

Ответ:

Объяснение:

n(O₂) = 2,5 моль

Vm = 22,4 л/моль

V(O₂) - ?

==========

V = Vm*n

V(O₂) = 22,4 л/моль * 2,5 моль = 56 л

Answer 2

Calculation of Oxygen Volume at STP

To calculate the volume of oxygen at standard temperature and pressure (STP) for a given amount of moles, we can use Avogadro's law. Avogadro's law states that equal volumes of gases, at the same temperature and pressure, contain an equal number of molecules.

The molar volume of any gas at STP is approximately 22.4 liters per mole. This means that one mole of any gas occupies a volume of 22.4 liters at STP.

Given that we have 2.5 moles of oxygen, we can calculate the volume using the following formula:

**Volume = Number of moles x M
