<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
