How many grams of hydrochloric acid should we use so we have exactly enough to react with 40g of sodium hydroxide? You'll need to write a chemical reaction, balance it, and then perform your calculation.

  1. Dear Sally,

    Here is the balanced equation
    HCL(aq) + NAOH(aq)---- NACL(s)+ H20(l)

    Number of moles in the NAOH(aq)=
    40/(23+16+1)
    =1
    as 1 mole of HCL will react with 1 mole of the Naoh solution
    number of mole of HCL required= 1

    Still remember that there is a equation
    mol= g/molar mass
    Let the number of grams of HCL needed be g grams
    the number of grams of HCL required=
    1= g/(1+35.5)
    g=36.5

    Therefore, 36.5 grams of HCL is required
    Hope it helps!!
