Dear mut 
Please provide the ans. 
Do not do such type of activity. 
The heat of neutralisation of strong acid and strong base is equal to - 57.8 kj/ mol.therefore ,the basicity of acid must be equal to one.For eg. HCl + NaOH = H2O + NaCl .So this HCl has one basicity which has heat of neutralisation around 57.8 kj /mol  
Good Luck
