The molar mass of two equally sized samples of unknown gaseous compounds is shown in the table. molar mass comparison gas molar mass x is 28 g/mol y is 44 g/mol at stp, which describes the density and effusion of both gases? a.)gas x has a higher density and effuses faster than gas y. b.)gas x has a higher density and effuses slower than gas y. c.)gas x has a lower density and effuses slower than gas y. d.)gas x has a lower density and effuses faster than gas y.

D.) Gas X has a lower density and effuses faster than Gas Y.

Explanation:

So, it is has a lower density of Y.

Thomas Graham found that, at a constant  temperature and pressure the rates of effusion  of various gases (∨) are inversely proportional to  the square root of their molar masses (M).

So, the gas with lower molar mass will effuse faster than gas of higher molar mass.

∴ Gas X effuses faster than Gas Y.

D.) Gas X has a lower density and effuses faster than Gas Y.

the old alchemists made significant contributions to science even though there starting premises were off a bit. their conclusions after failure would steer them into better directions for investigation. science is no more than close observation and the initial mistakes result in rethinking and retrying experiments.
