Question

Find the number of grams 4.00 moles of CU(CN)2 ​

Answer 1

Answer:

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
