      (Meaning it has twice the amount of solute or number of molecules per finished liter of solution). A 0.5 M solution is 1/2 as concentrated as a 1 M solution, etc. If we know the moles of a solute per liter of solution, we can easily compute the grams of the solute per liter. Suppose we have a hypothetical solute with a molecular wt. of 40.2 grams.

      In molecules we show bonding and non-bonding electrons. Atoms tend to react to get a full valence shell of electrons. Hydrogen (H) will have a complete valence shell with 2 electrons (1 pair) and most other atoms have 8 electrons (4 pairs) to get a complete valence shell. Our job is to figure out how to put the atoms and valence electrons ...

      When we measure volume, we use the liter. One liter is slightly larger than a quart (1 liter = 1.06 quarts). More commonly, in the laboratory, we use the milliliter (ml), which is one thousandths of a liter (1000 milliliters = 1 liter). ...
