I need help with a chemistry problem.?

Question

A solution contains 53.5 cm^3 of sucrose, C12H22O11,

density(1.587 g/cm^3) is dissolved into 230 ml of solution. Calculate

the molarity of the solution and mass/volume percent of sucrose in

the solution.

Answer 1

M1/M2 = V1/V2

There's a nice way to use to find the answer. Just rearange the formula to your needs. so it'll be something like :

M1= M2*V1/V2

Answer 2

Ans: fisrt calculat the mass of sucrose from relation d=m/v or m = dx v which comes out 84.9 g, than calculate the molecular mass of sucrose which is 370g/mol

and calculate the number of moles

   n= mass of sucrose /molecular mass

which are 0.24mol.

then calculate the molarity

  M= n/vol/dm3

M = 0.24 x1000/230 ml

M  1.08 molar

mass /volume % ?

    84.9 /53.5

   1.58 x 100 = 158 %

i hope u understand it
