The mass, in grams, of 2.50 mol of iron(iii) hydroxide is 225g
Mass is the measure of amount of matter in a substance or in a object
Here given data is mass iron(iii) hydroxide in mole = 2.50 mol and we have to find mass in gram = ?
The mass of one mole of Fe(OH)₂ = 89.85g/mol
So multiply by given mole by molar mass
2.50mol Fe(OH)₂ = 89.85g/mol Fe(OH)₂/1 mol Fe(OH)₂ = 225g Fe(OH)₂
