Question

Joyal took 5 moles of carbon atoms in a container and Sagar also took 5 moles of sodium atoms in another container of same weight,
(a) Whose container is heavier ?
(b) Whose container has more number of atoms ?​

Answer 1

Answer:

sagar containor is more heavier

Answer 2

Explanation:

$</p><p>\huge\underline{\underline{\sf{\purple{Required\:answer:}}}}$

Number of moles of carbon in Joyal's container = 5 mol

Weight of 1 mol of carbon atoms = 12

Now , Weight of 5 moles of carbon atoms = 12 × 5 = 60 g

Number of moles of sodium in sagar's container = 5 moles

Weight of 1 mol of Sodium = 23 g

Now , Weight of 5 moles of sodium = 23 × 5 = 115 g

By observing the above calculations . We can say that sagar's container is heavier compared to joyal's container.

And Now ,Coming to the number of atoms ;

Product of number of moles of substance and avogadro number (6.023×10²³) gives the number of atoms in that substance.

The number of moles of both taken atoms is same. So , Number of atoms will also be same.

Hence ,

sagar's container is heavier compared to joyal's container and Number of atoms present in both containers is same.
