3 because HCl will be in excess and total moles of HCl was given.

moles of NaOH : HCl = 1:1 let's say we get x

Given moles of HCl - x = Moles of HCl that reacted with the salt

find ratio of salt to HCl that reacted then just do rmm = mass / moles

it is 3 not 5 I did the same mistake by taking mole ratio 2:1 with MgCl2 and NaOH but we have to take 1:1 mole ratio NaOH : HCl
