Answer is: elements are always combined in the same proportion by mass.
Law of multiple proportions or Dalton's Law said that the ratios of the masses of the second element which combine with a fixed mass of the first element will be ratios of small whole numbers.
For example, nitrogen(I) oxide N₂O; m(N) : m(O) = 2·14 : 16 = 7 : 4.
Another example, water (H₂O) is made of two hydrogen atoms and one oxygen atom:
m(H) : m(O) = 2·1 : 16 = 1: 8.

There is no chemical formula for light energy because light is not a chemical.
Answer:
Follows are the solution to this question:
Explanation:
In this question, the given problem is used for secure accessing, drinkable water anywhere helps to solve personal filtered water. There are also both inexpensive and easy to access. Its components used mostly for everyone's manufacturing are long-lasting. Instead of just endangering users, those who protect the other, are the potential benefits to overall outweigh the potential.
Water=h20
=2.0*10^22 molecules
