Webvolume larutan = jumlah mol asam / konsentrasi asam. volume larutan = jumlah mol HCl / 0,1 M. volume larutan = (2,511 x 10^ (-8) mol) / 0,1 M. volume larutan = 2,511 x 10^ (-7) L atau 0,2511 mL. Jadi, untuk membuat pH larutan menjadi 7,6, kita perlu menambahkan sekitar 0,2511 mL HCl 0,1 M. Namun, perlu diingat bahwa ini hanyalah perkiraan kasar ...

WebJan 3, 2024 · Let's assume that you have 5 g of HCl in a 1.2 liter solution. Convert the expressions above to obtain a molarity formula. As mass / volume = molarity * molar … WebFirst, calculate the number of moles of strong base required to reach the equivalence point of the titration. Then, using the mole ratio from the balanced neutralization equation, convert from moles of strong base to moles of acid. Finally, divide the number of moles of acid by the given volume of the acid solution to find the concentration. flower girl dresses for 2 year old
