Actual yield of Fe2(So4)3 = 18.5g

2FePo4 + 3Na2SO4 -> Fe2(SO4)3 + 2Na3PO4

Mole of FePO4 = mass of it / its molar mass =
25 g / (55.8 + 31 + 16*4) = 0.166 mol

every 2 mole of FePO4 will form 1 mole of Fe2(SO4)3

Mole of Fe2(SO4)3 produced = 0.166 / 2 = 0.0829 mol

0.0829 * (55.8*2 + 3*(32.1+ 16*4)) = 33.148 g of Fe2(SO4)3

18.5 / 33.148 * 100 = 55.8%

Rosa preparo una disolución de agua salada mezclando 120 mg de agua con 5 mg de sal comun ¿ que concentración tiene la disolució
enot [183]

Concentration of the solution (% mass) = 4%

<h3>Further explanation</h3>

<em>Rosa prepared a salt water solution by mixing 120 mg of water with 5 mg of common salt, what concentration is the solution she prepare?</em>

<em />

<em />\tt \%mass=\dfrac{mass~solute}{mass~solution}\times 100\%<em />

mass solute=mass of salt=5 mg

mass solution :

mass solute(salt)+mass solvent(water) :

\tt 5~mg+120~mg=125~mg

\tt \%mass=\dfrac{5~mg}{125~mg}\times 100\%\\\\\%mass=4
