Question

How many molecules are in 4.62 moles of nitric acid (HNO3)?

Answer 1

Answer:

2.8x10^24

Explanation:

To convert moles to molecules, multiply the number of moles by Avagadro's number (6.02x10^23. Round if required.

4.62mol × 6.02x10^23 = 2.8x10^24

Answer 2

The number of molecules in 4.62 moles nitric acid has been $27.82\;\times\;10^2^3$.

The moles have been described as the mass of the compound with respect to the molar mass. According to the Avogadro law, the number of molecules present in a mole of sample has been equivalent to the Avogadro number.

The Avogadro number has been a constant quantity with the value of $6.023\;\times\;10^2^3$.

The Avogadro law has been given as:

$\rm 1\;mole=6.023\;\times\;10^2^3\;molecules$

Calculating for 4.62 moles nitric acid as:

$\rm 4.60\;mole=6.023\;\times\;10^2^3\;\times\;4.62\;molecules\\4.60\;mole=27.82\;\times\;10^2^3\;molecules$

The number of molecules in 4.62 moles nitric acid has been $27.82\;\times\;10^2^3$.
