Question

Яка килькисть речовыны азоту N2 миститься в судыни объёмом 20л (н. у.)?​

Answer 1

Ответ:

20л = 0.02м^3

0.02 * 1.16 = 0.232 кг азоту (232 грами)

Answer 2

Amount of Nitrogen in a 20L Container at Standard Temperature and Pressure (STP)

To calculate the amount of nitrogen gas (N2) in a 20L container at standard temperature and pressure (STP), we can use the ideal gas law equation:

PV = nRT

Where: - P = pressure - V = volume - n = number of moles of gas - R = ideal gas constant - T = temperature

At STP, the pressure (P) is 1 atmosphere (atm) and the temperature (T) is 273.15 K.

Using the ideal gas law, we can solve for the number of moles of nitrogen gas (N2) in the 20L container.

Calculation:

Given: - Volume (V) = 20L - Pressure (P) = 1 atm - Temperature (T) = 273.15 K

Using the ideal gas law equation:

PV = nRT

We can rearrange the equation to solve for the number of moles (n):

n = PV / RT

Substitute the given values:

n = (1 atm) * (20L) / (0.0821 L*atm/mol*K) * (273.15 K)

Calculating:

n ≈ 0.83 moles of N2

So, a 20L container at STP would contain approximately 0.83 moles of nitrogen gas (N2).
