Jika Kf air=1,86 derajat celcius/mol, larutan NaOH 4% (Ar Na=23, H= 1, dan O= 16) akan membeku pd suhu...

A = 4 gr NaOH p = 96 gr air kf = 1,86 mr NaOH = 40 i = alpha = 1 jawab : deltaKF = M x Kf x i 1,86 x 1000/96 x 4/40 x 1 = 10, 415 x 1,86 = 19,37
p = 96 gr air
kf = 1,86
mr NaOH = 40
i = alpha = 1
jawab :
deltaKF = M x Kf x i
1,86 x 1000/96 x 4/40 x 1 = 10, 415 x 1,86
= 19,37
smg benar ya, silahkan cek lagi perkaliannya
