462g
Explanation:
First, let us calculate the molar mass of Cu (CN) 2. This is illustrated below:
Molar Mass of Cu (CN) 2 = 63.5 + 2 (12+14) = 63.5 + 2 (26) = 63.5 + 52 = 115.5g/mol
Number of mole of Cu (CN) 2 given from the question = 4moles
Mass = number of mole x molar Mass
Mass of Cu (CN) 2 = 4 x 115.5
Mass of Cu (CN) 2 = 462g
