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

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

$M_{total} = M + m$

here we know that

$M = 84 amu$

so we will have

$M_{total} = 144 amu$

so we have

$144 = 84 + m$

$m = 60 amu$

Answer 2

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