Question

what volume in mL of 3.50 M FeCl3 contains exactly 100. g of FeCl3? the molar mass of FeCl3 is 162.3g

Answer 1

Answer #1

mole of FeCl3 = mass / molar mass = 100. g / 162.3 g / mole = 0.616 mole.

3.50 M FeCl3 means 1000 ml solution contains 3.50 mole FeCl3.

thus

volume of FeCl3 solution = 1000 ml * 0.616 mole / 3.50 mole = 176. ml (answer)
