Question

Укажіть об'єм 0,5 моль метану за (н. у.):

Answer 1

Ответ:

V(CH4) = 11,2 л

Объяснение:

Дано :

n(CH4) = 0,5 моль

Найти :

V(CH4) -?

1) V = n*Vm

Vm = 22,4 л/моль

V(CH4) = 0,5 моль * 22,4 л/моль = 11,2 л

V(CH4) =11,2 л

ответ : V(CH4) = 11,2 л

Answer 2

Methane Molar Volume at STP

The molar volume of a gas at standard temperature and pressure (STP) is the volume occupied by one mole of the gas at a temperature of 0 degrees Celsius and a pressure of 1 atmosphere.

The molar volume of 0.5 moles of methane at STP is approximately 11.2 liters.

This can be calculated using the ideal gas law, which states that at STP, one mole of any gas occupies a volume of 22.4 liters.

Therefore, for 0.5 moles of methane: ``` Volume = 0.5 moles * 22.4 liters/mole Volume = 11.2 liters ```

The molar volume of 0.5 moles of methane at STP is approximately 11.2 liters.

I hope this helps! If you have any other questions, feel free to ask.
