Answer 1

Find how many grams of KOH Are in 1 Mol. (K+O+H) {=56.105g/mol}
500ml is half a liter. If we multiply by 2 (remember to divide by two when you're done) we have .189 mold of KOH. Multiply .189 by 56.105 and we get 10.604 divide by two and we know how many grams of KOH are in the 500 ml solution. {5.302}
