Question

calculate molarity, molality and mole fraction of 28 percent aqueous solution of a solute with molar mass 11.5 g per mole and density is 1.25 g per mole

Answer 1

Step-by-step explanation:

Aight, I'mma give tell ya an easy way for this question. look at this Forumla

M=

`(10ad)/(m)`

a explains the percentage of aqueous solution

d is the density

m is the molar mass

right, let's just hop to it

M=10×28×1.25/11.5====> M=30.43
