today, i did a lab on the molar volume of hydrogen gas?

In this experiment, we poured around 10 mL of hydrochloric acid into a gas collection tube with water and measured the volume of gas to be around 20.9 mL.

would changing the molarity of the hydrochloric acid affect the final results? explain.


 Explain also how Avogadro’s hypothesis relates to the result obtained in this experiment

    The more concentrated the HCl, the more H2 is produced.

    It seems to me that unless you are interested in the number of molecules of gas, you could do this entire experiment and not refer to Avogadro’s hypothesis at all.
