Question

Yuk pagipagi nambah pahala:) boleh di bantu?

Answer 1

PH = 5 ; H^+ = 10^-5

H^+ = √ (Kw ÷ Kb) × (gr ÷ Mr) × (1000 ÷ mL)
10^-5 = √ (10^-14 ÷ 10^-5) × (gr ÷ 53,5) × (1000 ÷ 500)
10^-10 = 10^-9 × (gr ÷ 53,5) × 2
     gr  = (53,5 × 10^10) ÷ ( 2 × 10^-9)
         = 2,675

Answer 2

(a).6,675 gram itu jawabannya
