You have two balloons. One is filled with 27.0 grams of CO and the other is filled with 27.0 grams of carbon dioxide . Which balloon has more particles present?

1 Answer

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
