Which of the following has the largest mass? A)5.0 mol H₂O B)3.5 mol NH₃ C)8.0 mol C D)6.0 mol C₂H₂

Question

Quizplus · Accepted Answer

D) 6.0 mol of CS₂ has the largest mass because when comparing the molar masses of each compound or element given, CS₂ (carbon disulfide) has a significantly higher molar mass than the others listed. The molar mass of a compound is determined by the sum of the masses of all the atoms in one mole of the compound. CS₂, with its composition of one carbon atom and two sulfur atoms, has a higher molar mass compared to the simpler molecules and elements listed in the other options. Therefore, even though there are different amounts of moles for each substance, the higher molar mass of CS₂ means that 6.0 moles of it will have the largest total mass.
