The answer is 0.032 M
Molarity = number of moles/volume( in litres)
Volume = mass/density
Number of moles = mass/molecular mass
Molecular mass of HCL is 36.5g
Use the above formulae to get the answer if you still have any doubt do let me know

sory bro but in key they gave 32M
Actually I am sorry I kept the denisty in g/ml instead of litre to get it in litre multiply my above answer by 1000 you'll get 32M

Given:
Density of HCl=1.17g/cm³
Molarity=(density/molar mass)x1000 moles per liter
molar mass of HCl=[1+35.5]=36.5g/mol
Molarity=(1.17/36.5)x1000 =32.05M
∴Molarity of liquid HCl with density equal to 1.17 g/cc is 32.05
Density of HCl=1.17g/cm³
Molarity=(density/molar mass)x1000 moles per liter
molar mass of HCl=[1+35.5]=36.5g/mol
Molarity=(1.17/36.5)x1000 =32.05M
∴Molarity of liquid HCl with density equal to 1.17 g/cc is 32.05
