How many grams of calcium cyanide (Ca(CN)₂) are …
Since there are two cyanide groups in calcium cyanide, the total molar mass of Ca(CN)2 is 40.08 g/mol + 2(26.02 g/mol) = 92.12 g/mol. To find the mass in grams, we multiply the number of moles by the molar mass: 0.69 mol × 92.12 g/mol = 63.56 g. This value is closest to option a. 64 g, which is the amount of calcium cyanide contained in …
