The molecular mass of a formula unit of dimethylglyoxime is calculated as 116 g/mol.
The molecular mass can be given as the sum of the mass of each element in the formula unit of the compound.
The dimethylglyoxime is the compound with molecular formula, [tex]\rm C_4H_8N_2O_2[/tex].
The mass of each element in the compound is:
Substituting the mass in the formula unit of the compound as:
[tex]\rm C_4H_8N_2O_2=4(carbon)+8(hydrogen)+2(nitrogen)+2(oxygen)\\ C_4H_8N_2O_2=4(12)+8(1)+2(14)+2(16)g\\ C_4H_8N_2O_2=116\;g[/tex]
The molecular mass of dimethylglyoxime is 116 g/mol.
