Asolution is made using 80.0 g of toluene (mm 92.13 g/mol) and 80.0 g of benzene (mm 78.11 g/mol) what is the molality of the toluene in the solution?

a. 12.8 m
b. 10.9 m
c. 6.38 m
d. 5.43 m

B. 10.9 m

Explanation:

Molality of toluene = moles of toluene/mass in kilogram of benzene

Moles of toluene = mass/MW = 80/92.13 = 0.87 mole

Mass in kilogram of benzene = 80/1000 = 0.08kg

Molality of toluene = 0.87/0.08 = 10.9 m

the cellphone, they would then know if the killer would have contacted them or always hated them. or if it was a breakup. but if that is not the case, then it would be the clothing. to put in a bullet, it would have to be put in by hands. hands have finger prints which, would have giving you the answer of who done it.
