Question

Q:- Calculate the number of ions of the following compound:- 16g of H₂CO3​

Answer 1

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

$moles \: = \frac{16}{62.026} \\ = 0.2579563 \\ = 0.2580 \: moles$

1 mole = 6.02 x 10²³ ions

0.2580 moles = ?

=

$= \frac{0.2580 \times 6.02 \times 10 ^{23} }{1} \\ = 1.553 \times {10}^{23} \: ions$

Hence the number of ions in 16g H2CO3 = 1.553 x 10²³
