Answer:
118.70 g/mol or amu
Explanation:
Molar mass is calculated by adding up all of the masses of the individual atoms. This can be slightly shortened by using coefficients whenever there is a repeated element. In this case we would do as follows, inserting the atomic masses of each element in place of its symbol:
(Ni) + (C) + 3(O)
So
(58.693) + (12.011) + 3(15.999) = 118.70 g/mol or amu
