Question

2. Calculate the number of moles in 0.070 g of iron(III) hydroxide.

Answer 1

Explanation

The first step is to calculate the molar mass of iron (III) hydroxide.

The chemical for iron (III) hydroxide is Fe(OH)₃.

Fe(OH)₃ = Fe + 3(O + H)

From the periodic table, MM of (H = 1.00784 g/mol, Fe = 55.845 g/mol, O = 15.999 g/mol).
