Asked by Cali234

A gas of unknown identity diffuses at a rate of 83.3 mL/s in a diffusion apparatus in which carbon dioxide diffuses at the rate of 102 mL/s. Calculate the molecular mass of the unknown gas. Give your answers in units of g/mol to three significant figures.

Grahams Law: Rate of diffusionis inversely prop to sqrt of mass

102/83.3 = sqrt (M/44) (molmass CO2 is 44amu)

Mass= (102/83.3)^2 *44
