If 507 g FeCl2 were used up in the reaction FeCl2 + 2NaOH Fe(OH)2(s) + 2NaCl, how many grams of NaCl would be made?
Ket [755]
Number of moles of FeCl2 used = mass/ molar mass 
Number of moles = 507/126.751 = 4.
If one mole of Fe reacts with two moles of sodium 
Then 4 moles of Fe produces 8 moles of sodium.
Number of moles of sodium = mass/molar mass
Molar mass of sodium chloride = 23 +35.5 = 58.5 g/mol
Hence mass = 8 * 58.5 = 468 g. Hence Option A.

What is the concentration of a solution that has a volume of 2.5L and contains exactly 2.125 moles of calcium phosphate
Iteru [2.4K]

Answer:

0.85 mol/L.

Explanation:

  • Molarity is defined as the no. of moles of solute dissolved in a liter of the solution.

<em>M = (no. of moles of solute)/(Volume of the solution (L))</em>

no. of moles of calcium phosphate = 2.125 mol.

Volume of the solution = 2.5 L.

<em>∴ M of calcium phosphate</em> = (2.125 mol)/(2.5 L) = <em>0.85 mol/L.</em>
