Answer:

Approx. #14# #mol*L^-1#

Explanation:

We know that #1# #mL# of sulfuric acid has a mass of #1.73# #g#, of which #1.384# #g# is #H_2SO_4#.

So #"concentration"# #=# #"Moles of solute"/"Volume of solution"#

#(1.384*cancelg)/(98.079*cancelg*mol^-1)# #xx# #1/(1*cancel(mL)xx(10^-3L*cancel(mL^-1))# #=# #?? mol*L^-1#

#"98% sulfuric acid (w/w)"# has a density of #1.83*g*mL^-1#. What is the molarity of this solution.
