Answer 1

Molarity = moles of substance

                 volume in liters

 

          moles of H2SO4  = mass/ molar mass    

denisty = 1800g/L

            mass of H2SO4  98% of 1800= 1764g(this is mass of H2SO4 in 1L)

 molar mass= 2+32+64  =  98                              

moles =  mass/molar mass   =    1764/98

                                              = 18 moles

Therefore in !liter of H2SO4 molarity=   moles/volume in liters= 18/1L

            = 18M

Molarity =18M

So correct option will be 18 M...But their is printing mistake in option (2)... It will 18 M
