How many mols KOH do you have? That's mols KOH = M x L = ? How many mols HNO3 will that neutralize. The same number since the equation is 1 mol HNO3 to 1 mol KOH. M HNO3 = mols HNO3/L HNO3.
The dilution formula is c1v1 = c2v2 1.000*v = 0.600*1000 v = 600. Take 600 mL of the 1.000M and dilute to 1000 mL.
mols dichromate = M x L = ? Use the coefficients in the balanced equation to convert mols dichromate to mols FeSO4 Convert mols FeSO4 to mols Fe then to grams Fe. g Fe = mols Fe x atomic mass Fe. %Fe = (mass Fe/mass sample)*100 = ?
mols FeSO4 = grams/molar mass = ? Use the coefficients in the balanced equation to convert mols FeSO4 to mols KMnO4. M KMnO4 = mols KMnO4/L KMnO4. You know M and mols, solve for L and convert to mL.
