<u>Answer:</u>
<u>For a:</u> The number of molecules of iodine gas produced are
<u>For b:</u> The mass of iodine gas is produces is 26.9 grams.
<u>Explanation:</u>
We are given:
Moles of copper (II) chloride = 0.4235 moles
For the given chemical reaction:
By Stoichiometry of the reaction:
2 moles of copper (II) sulfate produces 1 mole of iodine gas
So, 0.4235 moles of copper (II) sulfate will produce = of iodine gas
According to mole concept:
1 mole of a compound contains number of molecules
So, 0.2118 moles of compound will contain = number of molecules
Hence, the number of molecules of iodine gas produced are
To calculate the number of moles, we use the equation:
We are given:
Moles of iodine gas = 0.2118 moles
Molar mass of iodine gas = 127 g/mol
Putting values in above equation, we get:
Hence, the mass of iodine gas is produces is 26.9 grams.
