Question

Calculate the molality ( m) of solution containing 30.5 g of ethylene glycol C2H6O2 dissolved in 185 g of water. SHOW WORK PLEASE

Answer 1

GIVEN

mass of solution (m) =30.5g

mass of solvent (ms) =185g

R.tc Malality (M) =?

sln

mr=C2H6O2

mr=12x2+1x6+16x2

=62

Malality =mX1000 /mrxms

M =30.5x1000/62x185

Malality =2.659
