Answer: 1.8 moles Fe and 2.7 moles are produced.
Explanation:
The balanced chemical reaction is:
According to stoichiometry :
3 moles of require 1 mole of
Thus 2.7 moles of will require=
of
Thus is the limiting reagent as it limits the formation of product and
is the excess reagent.
As 3 moles of give = 2 moles of
and 3 moles of
Thus 2.7 moles of will give =
of
and
of
Thus 1.8 moles Fe and 2.7 moles are produced.
<u>Answer:</u> The mass of water that should be added in 203.07 grams
<u>Explanation:</u>
To calculate the molality of solution, we use the equation:
Where,
m = molality of barium iodide solution = 0.175 m
= Given mass of solute (barium iodide) = 13.9 g
= Molar mass of solute (barium iodide) = 391.14 g/mol
= Mass of solvent (water) = ? g
Putting values in above equation, we get:
Hence, the mass of water that should be added in 203.07 grams
