Web5 de abr. de 2009 · Step 3. Molarity is number of moles per liter. Divide the 152.6 grams of the solute by the forumua weight (or molecular weight) of the solute, and you have the number of moles of solute. This number is therefore the molarity of the solution.

WebNormality is a behavior that can be normal for an individual (intrapersonal normality) when it is consistent with the most common behavior for that person. Normal is also used to describe individual behavior that conforms to the most common behavior in society (known as conformity).However, normal behavior is often only recognized in contrast to … Web9902. Just by eye we can see that the more digits we use the more the counts tend to group around the expected value. This is called the "Law of Large Numbers": in the long run random events tend to average out at the expected value. We see the same thing with two-digit pairs. So this increases our confidence that Pi is a normal number.
