Homework Help: Chemistry

Posted by ramire2 on Sunday, May 5, 2013 at 2:34am.

The density of concentrated sulfuric acid is 1.84 g/mL. If this corresponds to 18 M, what is the molality of the solution?

Molar mass= 98.
98 x 18 =1764g/L - 1.84 =1762.16/1000 = 1.76 kg
18/1.76=10.23 m

But my only options are:
a) 18 m
b) 95.5 m
c) 240 m
d) 0.240 m?
