Aluminum reacts with 42 g of iron(ii) sulfate. how many grams of iron are formed? aluminum sulfate is the other product?

= 15.44 g

Explanation:

The equation for the reaction;

2Al+3 FeSO4 → Al(2)(SO4)(3)+3Fe

We can find;

Moles of iron (ii) sulfate = 42 g/ 151.908 g/mol

                                       = 0.2765 moles

Mole ratio of iron (ii) sulfate : Iron = 3 : 3 = 1 : 1

Therefore;

Moles of Iron produced = 0.2765 moles

Mass of iron = 0.2765 moles × 55.845 g/mol

                     = 15.44 g

pure substance: iron,copper

impure substance: water,charcoal
