Consider Option (B) : 1 Mole of Silver. We know that : One Mole of Silver weighs 108 grams.

Consider Option (C) : 22.4 Liters of O₂ at STP. ...

Consider Option (D) : 6.022 × 10²³ Atoms of Carbon.

Answer 2

Answer:

Let us find each Option's Weight in order to come to a Conclusion which weighs the Least :

Consider Option

(A) : 2 gram atoms of Nitrogen

Gram Atomic Mass is the Mass of One Mole of Atoms of an Element

We know that : One Mole of Atoms of Nitrogen weighs 14 grams

⇒ One gram atom of Nitrogen = 14 grams

⇒ 2 gram atoms of Nitrogen = 28 grams

Consider Option

(B) : 1 Mole of Silver

We know that : One Mole of Silver weighs 108 grams

Consider Option

(C) : 22.4 Liters of O₂ at STP

We know that : 1 Mole of O₂ occupies 22.4 Liters of Volume at STP

We know that : One Mole of O₂ weighs 32 grams

⇒ 22.4 Liters of O₂ weighs 32 grams at STP

Consider Option

(D) : 6.022 × 10²³ Atoms of Carbon

We know that : One Mole of Carbon Atoms weigh 12 grams

We know that : One Mole of Atoms contain 6.022 × 10²³ Atoms

⇒ 6.022 × 10²³ Atoms of Carbon weighs 12 grams

Among the Given Options, Option (D) weighs the Least.
