Answer:
The answer to your question is 6.72 x 10²⁰ atoms
Explanation:
Data
Avogadro's number = 6.022 x 10²³ atoms
Volume = 22.4 L
Volume 2 = 25 ml
Number of atoms = ?
Process
1.- Convert mL to L
1000 mL ----------------- 1 L
25 mL ------------------ x
x = (25 x 1) / 1000
x = 25 / 1000
x = 0.025 L
2.- Use proportions and cross multiplication to find the answer.
22.4 L ----------------- 6.023 x 10²³ atoms
0.025 L -------------- x
x = (0.025 x 6.023 x 10²³) / 22.4
x = 1.51 x 10²² / 22.4
x = 6.72 x 10²⁰ atoms

Hope this helps! :)
So,
Formate has a resonating double bond.
In molecular orbital theory, the resonating electrons are actually delocalized and are shared between the two oxygens. So the carbon-oxygen bonds can be described as 1.5-bonds (option B). I'm not sure if option C is correct, however, because the likelihood of both delocalized electrons being in the area of one oxygen atom is less than 50%.<span />
