The lower molar mass the more particle for the same mass
hence, #CO# particles is more..

Explanation:

#"no. of mol" = "mass"/"molar mass"#

#"no. of CO" = (27 g) / (28 gmol^-1)#

#color(white)(xxxxxx)= 0.9643 mol#

#"no. of"color(white)x CO_2 = (27 g) / (44 gmol^-1)#

#color(white)(xxxxxx) = 0.6136 mol#

Since #mol# represents number of particles, so #CO# particles is more than #CO_2# particles
