When 0.28g of a basic oxide, MO, is reacted with 250cm3 of 0.05moldm–3 hydrochloricacid the excess acid required 50cm3 of 0.05moldm–3 sodium hydroxide solution forneutralisation. Which one of the following is the relative atomic mass of M?

3.12 g of MCl2 were dissolved in water and made up to one litre of solution. 25.0 cm3 of thissolution reacts with 7.5cm3 of 0.100M silver nitrate solution.
Which group 2 element is M?
The answer is Barium and i not sure how to find that?
