Respuesta :
I think its 60. I think you would subtract 144-84 to get the mass of the vinegar molecule.
Answer:
m = 60 amu
Explanation:
As we know that total mass is always conserved
So here we know that compound is of mass 84 amu initially
after reaction with vinegar molecule the total mass is given as
[tex]M_{total} = M + m[/tex]
here we know that
[tex]M = 84 amu[/tex]
so we will have
[tex]M_{total} = 144 amu[/tex]
so we have
[tex]144 = 84 + m[/tex]
[tex]m = 60 amu[/tex]
