Answer #1

Solution:- The given balanced equation is...

FeCl2(aq) + 2LiOH(aq) -----> Fe(OH)2(s) + 2LiCl(aq)

There is 1:2 between  Fe(OH)2 and LiOH. First of all we would convert the given grams of  Fe(OH)2 to moles and then using mol ratio we would calculate the moles of LiOH and finally using the given molarity the volume is calculated. The calculations would be done as...

1.00 g Fe(OH)2 x (1mol/89.86 g) x (2mol LiOH/1 mol Fe(OH)2) x (1L/0.223 mol) = 0.0998 L or 99.8 mL.
