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.

because of all the things that happen around the us, many people get into arguments which sadly could get physical, but we should actually make a change for that.

(b) which contains higher levels of vitamin b, oranges or spinach?

explanation:

you can eliminate a, c, and d because they are questions based on opinions.
