Question

find the molality and malarity of a 15 Solution of H2So4= 1.020gml
​

Answer 1

Answer:

density (d)= 1.02

%concentration= 15%

M= molecular weight

Molarity= 10 *d*X/ M

= 10*1.02*15/98

= 10.2*15/98

= 153/98

= 1.56.

Molality = 1000* molarity

------------------------

1000d - molarity*M

= 1560

------------------

1020 - 1.56*98

= 1.799
