Question

Assume you have 0.137 mol of dimethylglyoxime (used in the laboratory to test for nickel(II) ions). What mass of the compound is present?

Answer 1

Answer:15.91 g

Explanation:

Number of moles(n) =0.137 mol

Molar mass(M.m)=116.12 g/mol

Mass (m)????

n=m/M.m

m=n*M.m

m=0.137mol*116.12 g/mol

m=15.91 g
