Answer :
Answer:
0.071 mole
Explanation:
As discovered from Avogadro's hypothesis, 1 mole of any substance contains 6.02x10^23 molecules.
This simply means that 1 mole of H3PO4 also contains 6.02x10^23 molecules.
If 1 mole H3PO4 contains 6.02x10^23 molecules,
Then, xmol of H3PO4 will contain 4.3x10^22 molecules i.e
Xmol of H3PO4 = 4.3x10^22/6.02x10^23 = 0.071 mole
From the calculations made above, 4.3x10^22 molecules of H3PO4 have 0.071 mole of H3PO4

Final answer:
Using Avogadro's number, you can find there are approximately 0.71 moles in 4.3 x [tex]10^{22}[/tex] molecules of H3PO4.
Explanation:
To find out how many moles are in 4.3 x [tex]10^{22}[/tex] molecules of H 3 PO 4, you want to use Avogadro's number, which is 6.022 x [tex]10^{23}[/tex] molecules per mole. To find the number of moles:
Number of moles = (Number of molecules) / (Avogadro's constant)
4.3 x [tex]10^{22}[/tex] molecules H3PO4 / (6.022 x [tex]10^{23}[/tex] molecules/mole) = 0.71 moles H3PO4.
So, there are approximately 0.071 moles in 4.3 x[tex]10^{22}[/tex] molecules of H3PO4.
