tolong besertakan caranyaa

wt = 10 gr (Mr = 60)
wp = 90 mL = 90 gr (Mr = 18)
P° = 62 cmHg
P = ...................?

nt = wt/Mr = 10/60 = 0,17 mol
np = wp/Mr = 90/18 = 5 mol

Xt = nt/(nt+np) = 0,17/(0,17+5) = 0,17/5,17 = 0,033
Xp = 1 - Xt = 1 - 0,033 = 0,967

P = Xp.P° = 0,967.62 = 59,954 = 60 cmHg

jawaban : D
