Answer:
A molecular formula tells us what atoms and how many of each type of atom are present in a molecule.
Explanation:
If only one atom of a specific type is present, no subscript is used.
For atoms that have two or more present, a subscript is written after the symbol for that atom.
Molecular formulas do not indicate how the atoms are arranged in the molecule.

To determine the volume of both concentration of vinegar, we need to set up two equations since we have two unknowns.
For the first equation, we do a mass balance:
mass of 100% vinegar + mass of 13% vinegar = mass of 42% vinegar
Assuming they have the same densities, then we can write this equation in terms of volume.
V(100%) + V(13%) = V(42%)
we let x = V(100%)
y = V(13%)
x + y = 150
For the second equation, we do a component balance:
1.00x + .13y = 150(.42)
x + .13y = 63
The two equations are
x + y = 150
x + .13y = 63
Solving for x and y,
x = 50
y = 100
Therefore, you need to mix 50 mL of the 100% vinegar and 100 mL of the 13% vinegar.
