Question

The average mass of 1 baking soda compound is 84 amu After it reacts with 1 vinegar molecule the total mass of the product is 144 amu What is the mass of the one vinegar molecule

A 60 amu
B 84 amu
C 144 amu
D 228 amu

Answer 1

I think its 60. I think you would subtract 144-84 to get the mass of the vinegar molecule.

Answer 2

m = 60 amu

Step-by-step 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

`M_(total) = M + m`

here we know that

`M = 84 amu`

so we will have

`M_(total) = 144 amu`

so we have

`144 = 84 + m`

`m = 60 amu`
