Question

определить массу H2 объемом 40 литров. решите пожалуйста

Answer 1

m = n*M

M(H2) = 2 г/моль

n = V/Vm

n(H2) = 40 л/22,4 л/моль = 1,8 моль

m(H2) = 2 г/моль * 1,8 моль = 3,6 г

Ответ: 3,6  г

Answer 3

Calculating the Mass of H2 with a Volume of 40 Liters

To determine the mass of H2 with a volume of 40 liters, we can use the ideal gas law equation, which states:

PV = nRT

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

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

n = PV / RT

Given that the volume (V) is 40 liters, we need to know the pressure (P) and temperature (T) to calculate the number of moles of H2. Once we have the number of moles, we can then calculate the mass of H2 using the molar mass of hydrogen.

Let's proceed with the calculation using the ideal gas law equation and the provided information.

Calculation Steps:

1. Pressure (P): - The search results do not provide the pressure value required for the calculation. Without this information, it's not possible to calculate the mass of H2 accurately.

2. Temperature (T): - The search results also do not provide the temperature value needed for the calculation.

Without the specific pressure and temperature values, it's not feasible to calculate the mass of H2 with a volume of 40 liters accurately. If you have the pressure and temperature values, please provide them, and I'd be happy to help you with the calculation.
