If you need to produce 9.75 moles of iron(III) oxide (Fe2O3), how many moles of iron will be required? *

Thus 9.75 moles of iron will be required.

Explanation:

The balanced chemical reaction is:

According to stoichiometry :

2 moles of are produced by= 2 moles of

Thus 9.75 moles of are produced by=  of

Thus 9.75 moles of iron will be required.

a gas, having a molecular weight of 13 kg/kmol and a kinematic viscosity of 0.25 cm2/s, flows through a pipe 0.25 m internal diameter and 5 km long at the rate of 0.4 m3/s and is delivered at atmospheric pressure.
