Answer:

The answer is 0.32 moles

Explanation:

To find the number of moles given the number of entities we use the formula

[tex]n = \frac{N}{L} \\ [/tex]

where n is the number of moles

N is the number of entities

L is the Avogadro's constant which is

6.02 × 10²³ entities

From the question

N = 1.93 × 10²³ particles

We have

[tex]n = \frac{1.93 \times {10}^{23} }{6.02 \times {10}^{23 } } \\ = 0.320598006...[/tex]

We have the final answer as

0.32 moles

Hope this helps you

Answer :

No. of particles of Na₃PO₄ = 1.93×10²³

We have to find number of moles of the given compound[tex].[/tex]

Number of moles cam be found by using this formula :

[tex]\bigstar\:\boxed{\bf{\purple{n=\dfrac{N}{N_A}}}}[/tex]

  • n denotes number of moles
  • N denotes number of particles
  • [tex]\sf{N_A}[/tex]denotes avogadro's constant

We know that,

  • [tex]\bf{N_A}[/tex] = 6.022×10²³

★ Calculation :

➠ n = N/[tex]\sf{N_A}[/tex]

➠ n = (1.93×10²³)/(6.022×10²³)

➠ n = 0.32 moles

★ Explore More :

  • n = weight / Molar mass
  • n = volume / 22.4

Hope It Helps!
