Question: A flask equipped with a valve contains 3.0 mol of H2 gas. You introduce 3.0 mol of Ar gas into the flask via the valve

A flask equipped with a valve contains 3.0 mol of H2 gas. You introduce 3.0 mol of Ar gas into the flask via the valve and then seal the flask.
a. What happens to the pressure of just the H2 gas in the flask after the introduction of the Ar? If it changes, by what factor does it do so?
b. How do the pressures of the Ar and the H2 in the flask compare?
c. How does the total pressure in the flask relate to the pressures of the two gases?
