Can someone please check my work? Question: 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 My Answer: Balanced Equation: Sn + 2HCl → SnCl2 + H2 Mass of Tin: 7.31 * ( 2.5 * 3 * 3.5 ) = 191.89 g Mass of HCl: (2 * 191.89/ 118.7) * 36.5 = 118 g HCl.
