38% of HCL is dissolved to make solution having density equal to 1.125g/cm^3 . Find molarity of solution
Asked by Bhanupriya Khurana | 07 Jul, 2013, 07:55: PM
Expert Answer
molarity = moles / vol.
moles = given mass / molar mass ..... 100/36.5
to find volume, d = mass/vol.
or 1.125 = 38 / vol..... or vol = 38 / 1.125
now, substitute the values in the first formula and calculate.
molarity ;
100/36.5
------------ M.
38 /1.125
