Stoichiometry

Q1: Avogadro's number is equal to

A 6.023 x 1023 molecules/kg.mole.

B 6.023 x 1023 molecules/gm.mole.

C 6.023 x 1016 molecules/kg.mole.

D 6.023 x 1026 molecules/gm.mole.

ANS:B - 6.023 x 1023 molecules/gm.mole.

Avogadro's number, denoted as 𝑁𝐴NA​, is a fundamental constant used in chemistry and physics to represent the number of constituent particles (usually atoms or molecules) in one mole of a substance. The correct value for Avogadro's number is approximately 6.023×10236.023×1023 particles per mole. It is often expressed with units such as molecules/mole or atoms/mole. So, the correct option is: 6.023×10236.023×1023 molecules/mol
