c. An Analytical laboratory at SMU has a bottle of concentrated HCI solution labelled, specific gravity of 1.2g/cm and which is 37% (w/w) HCI. M(HCI)= 36.46g/mol. From this 0.6mol,was carefully pipetted out into a 100ml standard flask and made up to the mark. Exactly 0.350g of pure sodium carbónate (Na CO3) M =105.988g/mol was dissolved into the above 100ml made up solution of HCI and the following reaction óccurred: Na2CO3 + 2HCI - 2NACI + CO2(g) + H20 i. What is the molar concentration of this HCI solution What is the resultant concentration of HCI in 100ml
