<u>Answer:</u> The mass of formed will be 79.9 grams.
<u>Explanation:</u>
To calculate the number of moles, we use the equation:
.....(1)
Given mass of iron(II) sulfate = 50. g
Molar mass of iron(II) sulfate = 151.9 g/mol
Putting values in equation 1, we get:
The chemical equation for the formation of follows:
By Stoichiometry of the reaction:
1 mole of iron (II) sulfate produces 1 mole of
So, 0.33 moles of iron (II) sulfate will produce = of
Now, calculating the mass of by using equation 1, we get:
Molar mass of = 242 g/mol
Moles of = 0.33 moles
Putting values in equation 1, we get:
Hence, the mass of formed will be 79.9 grams.
