From the calculations and the data presented, the total volume in the flask is 100cm^3
What is neutralization?
A neutralization occurs between an acid and a base to yiled salt and water only.
The reaction equation here is; HCl + NaOH -----> NaCl + H2O. Now, the volume of HCl used is obtained from;
2 * 20 * 1/0.5 * 1 = 80 cm^3
Total volume in the flask = 80 cm^3 + 20cm3 = 100cm^3
