How many grams of Aluminum will react w/ 1 liter of a 1M solution of Fe^3+?
wat steps do i need to take to solve this?
Al + Fe+3==> Fe+2 + Al+3.
Here are the steps for solving a stoichiometry problem.
Step 1. Write the balanced equation. You have the equation; it must be balanced.
Al + 3Fe+3==> 3Fe+2 + Al+3.
Step 2. Convert 1 L of 1 M solution to mols.
M = mols/L; therefore, 1 L x 1 M = 1 mol
Step 3. Convert mols of what you have (in this case, 1 mol Fe+3) to mols of what you want (in this case Al).
Use the coefficients in the balanced chemical equation.
mols Al = 1 mol Fe+3 x (1 mol Al/3 mols Fe+3)= 1/3 mol Al.
Step 4. Now convert 1/3 mol Al to grams remembering that grams = mols x molar mass = mols Al x molar mass Al.
I hope this helps.
oh yes
this helps a lot
thanx
