Question

Problem 5.6. The canal bringing water from Kurtboğazı Dam to Ankara is 10! km long, before water enters a closed conduit. The width of the canal is 3.4 m Assuming the evaporation amounts obtained from a Class A pan in the region

Answer 1

ANSWER:-

a)-first we have to calculate the theoretical yield of of Fe

molecular weight of Fe₂O₃ is 159.6 gm and given weight is 150 g moles of Fe₂O₃ is one

molar mass of Fe is 55.8 g moles of Fe is 2 ,

so,

150 g Fe₂O₃ * 1 mole Fe₂O₃/159.6 g * 2 mole Fe / 1 mole Fe₂O₃ * 55.8 g Fe/1 mole Fe

=104.9 g of Fe (theoretical yield)

b)- percent yield = actual yield/theoretical yield * 100

= 87.9 g/104.9 g *100

percent yield = 83.79 %
