Which sample has the largest mass?
(A) I mole of marshmallows
(B) I mole of Pb (lead) atoms
(C) 1 mole of C02 (carbon dioxide) molecules
(D) All of these have the same mass.



Answer :

Answer: 1 mol of marshmallows

Explanation:

No of moles of a substance = (Mass of substance / Molar mass of substance)

Here, all given substances have equal moles, i.e, 1 mole.

Hence,mass of substance variation is directly related to their molar masses, the higher the molar mass, the greater is the mass of that substance.

Here, we know, order of the masses, in descending order are-

Marshmellows > Pb> CO2

Therefore, Masses are in same order-

Marshmellows > Pb> CO2

Thus, 1 mole of marshmellows has largest mass.
