A 250 mL beaker is submerged in a large container of Liquid X and turned upside down, and another 250 mL beaker is submerged and turned upside down in a large container of Liquid Y. Hydrogen (H2) gas is bubbled into each upside-down beaker until 100 mL of liquid has been displaced. The masses m X and my of hydrogen inside each beaker is then chemically determined.

a. mx will be greater than my
b. m x will be less than my
c. mx will be equal to my
d. It's impossible to predict whether mx or my will be greater without more information.
