Question

Calculate the number of moles in 5.96 g KOH

Answer 1

Collection of data mass(m) =5,96 (given) Molarmass(M) =1(39)+1(16)+1(1)=56 (we use the periodic table to calculate the molar mass of KOH) Moles(n) =?? (It is wat we have to calculate) We can use the formula n=m/M Therefore n=5,96/56=0,10643moles

Answer 2

? moles KOH = 5.96 x (molar mass of KOH/1 mol)
