Question

How many moles is 1.50x10^23 molecules of NH3?

Answer 1

To find the number of moles of NH3 in 1.50x10^23 molecules, divide the number of molecules by Avogadro's number, yielding approximately 0.249 moles of NH3.

Step-by-step explanation:

To determine how many moles of NH3 are present in 1.50x10^23 molecules of NH3, we need to use Avogadro's number, which is 6.022x10^23 molecules per mole.

The calculation to find the number of moles would be:

Number of moles = (1.50x10^23 molecules of NH3) / (6.022x10^23 molecules/mol)

By dividing the number of molecules by Avogadro's number, we get:

Number of moles = 0.249 moles of NH3 (rounded to three significant figures)

Answer 2

The number of moles that are 1.50 x10^23 molecules of NH3 are

=0.249 moles

calculation

The number of moles is calculated using Avogadro's law constant

that is According to Avogadro's law

1 moles of a substance = 6.02 x10^23 molecules

? moles = 1.50 x10^23 molecules

by cross multiplication

= [( 1.50 x 10^23 molecules x 1 moles) / (6.02 x10^23)] = 0.249 moles
