PQ-L. pnceptuci Which sample has the largest mass? a) 1 mole of marshmallows (C) 1 mole of COz (carbon dioxide) molecules b) 1 mole of Pb (lead) atoms d) All of these have the same mass

Answer :

The sample which have the largest mass is the correct option is a)   1 mole of marshmallow.

The expression for number of moles is given as follows :

number of moles = mass / molar mass

mass = moles × molar mass

molar mass of marshmallow = 210.14 g/mol

molar mass of carbon dioxide = 44 g/mol

molar mass of Pb = 207.2 g/mol

it is clear form the above equation that the sample which has the larger the molar mass has the largest mass. the order of the mass in the following sample is given as :

marshmallows > Pb > CO₂

Thus the 1 mole of the marsh mallows has the largest mass among the following sample.
