Question

Salman took 7moles of Na and arvind took 7moles of iron in different containers

Which container weighs more

Answer 1

To solve the question:

Mass of substance = Number of moles of substance × Atomic mass

• Mass of substance in Salman's container:

             7 × 23 = 161 grams of Sodium..

• Mass of substance in Arvind's container:

             7 × 56 = 392 grams of Iron..

Hence, it can be concluded that Arvind's container (of iron) weighs more than Salman's container (of sodium)..
