Question
Which of the following pure copper samples contains the largest number of
atoms?
Sample A: 6.70 g
Sample B: 0.110 mol
Sample C: 7.83 x 1022 atoms
Answer:
Correct option is
D
1 g of B(s)
Larger is the number of moles, larger is the number of molecules.
As molar mass of B is lowest (=11 g), it will have larger number of moles. Hence, its 1 g will have highest number of molecules and moles.
Answer:d
