What is the pressure in a 19.1 L cylinder filled with 0.684 mol of nitrogen gas at a temperature of 326 K ?

The hydrogen sample has a pressure of 0.957 atmospheres.

Explanation:

Let consider that the hydrogen sample behaves ideally, the equation of state for ideal gases is:

(1)

Where:

- Pressure, in atmospheres.

- Volume, in liters.

- Molar quantity, in moles.

- Temperature, in Kelvin.

- Ideal gas constant, in atmosphere-liters per mole-Kelvin.

If we know that , , and , then the pressure of the hydrogen sample is:

The hydrogen sample has a pressure of 0.957 atmospheres.

it is to be noted that an alpha particle is an helium nucleus. so it contains 2 protons 2 neutrons and has a mass number of 4. when alpha decay particles are ejected from the nucleus it gets transformed into an atom which has atomic number less than 2 and a mass number less than 4.

an equation that could represent alpha decay is radium 226 decay of alpha particle forms radon 222.
