DiketahuiKonsentrasi H2SO4 = 49%
BJ H2SO4 = 1,3 kg/L
MR H2SO4 = 98
Vencer = 260ml
Mencer = 0,05 M
ditanya
Vpekat
Jawab
M H2SO4pekat = konsentrasi(%) x bj x 10 / MR = 49% x 1,3 x 10 / 98 = 6.5 M
Vpekat x Mpekat = Vencer x Mencer
Vpekat x 6.5 M = 260 mL x 0.05 M
Vpekat x 6.5 M = 13
Vpekat = 13 / 6.5 = 2mL
maaf kalo salah
