Answer:
175.33 g.
Explanation:
The balanced equation of reaction is given below;
FeCl3 + 3NaOH ---------> Fe(OH)3 + 3NaCl.
From the balanced equation of reaction we can see that one mole of FeCl3 reacts with three moles of sodium hydroxide to produce 3 mole of sodium chloride,NaCl and one mole of Fe(OH)3.
To calculate for the number of grams we will be needing the molar mass of Sodium chloride.
Molar mass of sodium chloride,NaCl= 22.989769 + 35.453 = 58.442769 grams per mole. Approximately, 58.443 grams per mole.
Therefore, the number of moles,n= mass/ molar mass. Recall that we have three(3) moles of Sodium chloride as the product. Hence,
3 mol = mass(in grams)/ molar mass(in grams per mol).
==> 3 = mass(in grams)/ 58.443 (grams per mol).
===> Mass in grams = 58.443 (grams per mol) × 3 mol.
Mass in grams = 175.33 grams.
