<u>Answer:</u> The number of molecules of carbon dioxide gas are
<u>Explanation:</u>
To calculate the molar solubility, we use the equation given by Henry's law, which is:
where,
= Henry's constant =
= molar solubility of carbon dioxide gas
= pressure of carbon dioxide gas = 0.250 atm
Putting values in above equation, we get:
To calculate the number of moles for given molarity, we use the equation:
Molarity of carbon dioxide =
Volume of solution = 0.550 L
Putting values in above equation, we get:
According to mole concept:
1 mole of a compound contains number of molecules
So, moles of carbon dioxide will contain =
number of molecules
Hence, the number of molecules of carbon dioxide gas are
Answer:
5*10²⁴ chlorine atoms are found in 8.3 moles of chlorine.
Explanation:
Avogadro's Number or Avogadro's Constant is called the number of particles that make up a substance (usually atoms or molecules) and that can be found in the amount of one mole of said substance. Its value is 6.023*10²³ particles per mole. Avogadro's number represents a quantity without an associated physical dimension, so it is considered a pure number that allows describing a physical characteristic without an explicit dimension or unit of expression. Avogadro's number applies to any substance.
Then you can apply the following rule of three: if 1 mole of the compound contains 6.023 * 10²³ atoms, 8.3 moles of the compound how many atoms does it have?
amount of atoms≅ 5*10²⁴ atoms
<u><em>5*10²⁴ chlorine atoms are found in 8.3 moles of chlorine.</em></u>
