Question

(b) Raunak took 5 moles of carbon atoms in a container and Krish also took also 5 moles of sodium atoms in
another container of same weight.
(in) Whiner has more number of at​

Answer 1

Answer:

Explanation:

Number of moles of carbon in Raunak's container = 5 mole

Weight of 1 mole of carbon atoms = 12

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

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

Weight of 1 mole of Sodium = 23 g

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

By observing the above calculations . We can say that Kris's container is heavier compared to Raunak'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 ,

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

FORMULA =N=M/M

Answer 2

Answer:

Number of moles of carbon in Raunak'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 krish'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 Krish's container is heavier compared to Raunak'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 ,

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