TREUse the balanced equation to solve the problem.Fe(NO3)3 + 3NaOH → Fe(OH)3 + 3NaNO3106g Fe(OH)3 are made in this precipitation reaction.How many moles of NaOH reacted?mol

Respuesta :

Explanation:

Fe(NO3)3 + 3NaOH → Fe(OH)3 + 3NaNO3

First, let's transform 106 g of Fe(OH)3 into moles using its molar mass (106.87 g/mol) and the following formula:

n = m/MM

n = 106/106.87

n = 1 mol

The equation tells us that

3 moles of NaOH produce 1 mol of Fe(OH)3.

Answer: 3 mol
