Question

esita took 5 moles of carbon atoms in a container and salini tools 5 moles of sodium aton in another container of the same weight.
a. whose container is heavier
b. whose container has more no of atoms.​

Answer 1

Answer:(a)salini's container is heavier

(b)both have same no. of atoms

Explanation:(a)esita took 5 moles of C

1 mole of C=12g

5moles of C=12×5=60g

On the other hand,salini took 5 moles of Na

1 mole of Na=23g

5 moles of Na=23×5=115g

Thus, salini's container is heavier...

(b) acc. to mole concept, 1 mole=6.022×10²³atoms or molecules for every element

So, 5 moles of each element=5×6.022×10²³ atoms.....thus they both have same no. Of atoms.........hope it will help you:)
