Answer:
= 1.553 x 10²³ ions
Explanation:
One mole of a compound or a substance consists of 6.02 x 10²³ ions. 6.02 x 10²³ is also referred to as Avogadro's number/constant.
From the above question, we have been asked to determine the number of ions in 16g of H₂CO3.
The relative formula mass (RFM) of H₂CO3 is 62.026 u:
Derived as;
H₂CO3 = (2 x 1.008) + (12.01 x 1) + (3 x 16.00) u
= 62.026 u.
Number of moles = Mass/RFM
[tex]moles \: = \frac{16}{62.026} \\ = 0.2579563 \\ = 0.2580 \: moles[/tex]
1 mole = 6.02 x 10²³ ions
0.2580 moles = ?
=
[tex] = \frac{0.2580 \times 6.02 \times 10 ^{23} }{1} \\ = 1.553 \times {10}^{23} \: ions[/tex]
Hence the number of ions in 16g H2CO3 = 1.553 x 10²³
