#44.009g#

Explanation:

Finding the mass of a molecule is quite simple: add up the mass of the atoms that make it up. #CO_2#, for example, has one carbon and two oxygen.

Using mass numbers from the RSC periodic table, the total mass per mole is

#1 * 12.011gmol^-1 + 2 * 15.999gmol^-1 = 44.009gmol^-1#

Because there is only one mole of #CO_2#,

#44.009g/(mol) * mol = 44.009g#
