When pоtаssium cyаnide (KCN) reаcts with acids, a deadly pоisоnous gas, hydrogen cyanide (HCN) is produced according to the following equation: 2 KCN(aq) + H2SO4(aq) → K2SO4(aq) + 2 HCN(g) If 30.5 mL of a 0.250 M KCN solution is reacted with an excess of H2SO4, calculate the amount of HCN formed (in grams).
