Question

В баллоне объемом 100 л находится 2 г кислорода при температуре 47 каково давление газа в баллоне

Answer 1

Решение. P*V=(m/M)*R*T; P=(m/M)*((R*T)/V); m=2*10^-3; M=32*10^-3; R=8,31; T=320;V=100*10^-3;

Answer 2

Calculating Gas Pressure in a Cylinder

To calculate the gas pressure in the cylinder, we can use the ideal gas law formula:

PV = nRT

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

Given: - Volume (V) = 100 L - Number of moles (n) = 2 g - Temperature (T) = 47°C

First, we need to convert the temperature from Celsius to Kelvin: T(K) = T(°C) + 273.15

T(K) = 47 + 273.15 = 320.15 K

Now, we can calculate the pressure using the ideal gas law formula: P = (nRT) / V

Substitute the given values: P = (2 * R * 320.15) / 100

Let's calculate the pressure using the ideal gas constant R.
