dissolve the whole 49.8 g of the compound Completely composed of Al and Zn requires 600 ml of 2M HCl and 1m H2SO4 solution a) calculation block for each metal in A b) for 24.9 g. Combination A reacts with excess HNO3 solution the reaction ends up producing 17.92 devices including NO and NO2 (level). Mass of salt produced and number of moles of HNO3 reacted

93.2 ml + 3920 ml = 4013 ml total  

(93.2 ml) * (2.03 m) / (4013 ml) = 0.0471 m

the volume in in l of the diluted solution would be 0.0471 m.

"among the transition metal elements, manganese and zinc have a slight lowering of electronegativities. the reason behind this is that the nuclear charges of these elements are slightly weaker than the other transition metal elements due to the way their valence electrons are filled up. both manganese and zinc have their valence electrons filled up to the 4th shell with 1 pair of electrons (4s2) completely occupying it. although the electrons in the 3rd shell (3d) are yet to be paired since the outer most shell is filled up, the ability of the nucleus to attract electrons is lessened. hence,   the electronegativity (or the ability to attract electrons) is lessened."
