Answer: Divide the mass of the first dissolved component by the solution mass, and then multiply the result by 100 to calculate the mass percentage. In our example, the first dissolved compound is NaCl; the mass percent is (10 g / 136 g) x 100 percent = 7.35 percent.

Explanation:
We assume you are converting between grams Water and mole.
You can view more details on each measurement unit:
molecular weight of Water or mol
The molecular formula for Water is H2O.
The SI base unit for amount of substance is the mole.
1 grams Water is equal to 0.055508435061792 mole.
Note that rounding errors may occur, so always check the results.
Valence electrons are the electrons in the outermost shell of an element on the periodic table. Atoms want to be able to have a full outer shell and they can share or trade electrons in order to achieve this. Valence electrons are also super super important in chemical reactions. The number of valence electrons determines what group that specific atom or element is in on the periodic table. This affects the reactivity of the element.
