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.

Sn + HCl → SnCl2 + H2

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
