Answer: 48.4 g of will be produced from 25.5 g of iron
Explanation:
To calculate the moles :
The balanced chemical reaction is:
According to stoichiometry :
2 moles of require = 3 moles of
Thus 0.455 moles of will require= of
Mass of
Thus 48.4 g of will be produced from 25.5 g of iron
Concentration Definition. In chemistry, concentration refers to the amount of a substance per defined space. Another definition is that concentration is the ratio of solute in a solution to either solvent or total solution. Concentration usually is expressed in terms of mass per unit volume.
Concentration = no of moles of solute/solvent
