38% of HCL is dissolved to make solution having density equal to 1.125g/cm^3 . Find molarity of solution

Asked by Bhanupriya Khurana | 7th 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
