its b only

Answer 2

Answer:

molarity is mol conc. per litre

no. of moles =given wt(6g)/molecular wt

for l) urea molecular weight= 60.6g

ll) acetic acid molecular wt=60.052

ll l) propanol molecular weight =60.092

ll) is less moles after we calc so its b take correct and exact values

if u take approx ull get equal actually approximately all are equal but exactly differ with small magnitude
