Answer:
The correct answer is 12.43 Liters.
Explanation:
Based on the given question, the volume V₁ occupied by the sample of carbon dioxide gas is 14.2 liters at temperature (T₁) 65 degree C or 65+273 K = 338 K.
The gas is cooled at a temperature (T₂) 23 degree C or 273+23 K = 296 K
The volume of the gas (V₂) after cooling can be determined by using the formula,
V₁/T₁ = V₂/T₂
14.2/338 = V₂/296
0.0420 = V₂/296
V₂ = 0.0420 * 296
V₂ = 12.43 Liters.

In 58.2 grams of Na there is 1.51 x 10^24 atoms.
<h3>Mole calculation</h3>
To calculate the amount of atoms present in a mass sample, it is necessary to have knowledge of the molar mass of the element and Avogadro's constant, used in such a way that:




Now, with the value of the number of moles, just calculate the number of atoms present, so that:



So, in 58.2 grams of Na there is 1.51 x 10^24 atoms.
