How many grams of hydrochloric acid will react completely with a block of tin that is 2.5 cm by 3.0 cm by 3.5 cm, if the density of tin is 7.31 g/mL? Show all steps of your calculation as well as the final answer.
let d = m / V m = Vd = (2.5 x 3.0 x 3.5)cm³ x 7.31 g/cm³ m = 191.9 g this is the mass of tin
the balanced chemical equation is . Sn(s) + 2HCl(aq) --> SnCl2(aq) + H2(g) 191.9g. .m=.?g so it is 191.9g Sn x (1 mol Sn / 118.7 g Sn) x (2 mol HCl / 1 mol Sn) x (36.5 g HCl / 1 mol HCl) = 120g HCl the mass of HCl =120g
