how do I calculate the moles of a acid added to a sample

Question

rane · Answer

moles = molar mass/ molecular mass 

so u can use the mass of the acid given and its molecular formula (if its not given) then u can use 
the given mass of the solutions and find its moles 
then use its moles to find the moles of the acid ==> unknown/known * moles (of solution) 

unknown & known are the ratios of the acid and solution, that are used to balance the equation. 

if u still dont know let me nkow i'll explain it using an example :)

thank you ! can you please use an example 
im working on a titration , I have to calculate the moles of acid added to the sample , then calculate the moles added to neutralize the excess solid . calculate the moles of acid that were neutralized by a tums tablet (antacid) . use the moles of acid neutralized by the piece of tablet to calculate the mole of acid that could be neutralized by the entire tablet .
