# N Cv

## N Cv

I have a total chemistry test, specify n = m / M, n = cV? 3

what's that ? What units are used to measure each and how is the pH calculated?

n refers to the number.

n = m / M

m is equal to m (unit is gram)

M refers to m molecules (unit is gram / mole)

There the gram was divided by the value, the molar unit was obtained.

n = CV

c refers to molar concentration (is unit / liter)

V refers to volume (liters)

In this case, multiplying a liter by a liter gives one unit.

what's that ?

A mole is a quantity of pure substance containing the same number of chemical units. In other words, it's just a unit of measurement.

To calculate the pH of an acidic solution:

First you need to know the H + concentration of your solution. Then find the negative logarithm of your H + concentration.

An example:

0.1 MHCL

pH = Log (0.1)

PH = 1

w To calculate the pH of an alkaline solution:

First, you need to know the concentration of OH in your solution. If you take the negative logarithm of OH concentration, you get pOH. Lowering the pH to 14 gives the pH of the solution.

An example:

0.1 M NaOH

pOH = Log (0.1)

POH = 1

PH = 14 POH

PH = 14 1

PH = 13

To better understand how the pH of a solution is calculated, try recalculating Henderson Heilbach's equation.

I now! For your health!

Even if ** in fact ** is wrong, you can only think of ■■■■■ as numbers. Like 20, a thousand or a million. But the mole is 6.022 * 10 23. We use n to denote quantity, N to denote quantity.

n = m / M

That is, the sum is equal to m divided by m by mol. Is it fair to say that many cars sit on one big wheel, a total of 400 kg, when each car weighs 100 kg? The number of vehicles is n (or atoms), m is the total m of the ferrous wheel (or m is the total of the specimens) and we know that M is per car (m per mol).

n {mol} = m {g} / M {(g / mol)

Second, it can be easy to see from a person's point of view. A room is 100 m 3 in size, and we know that there are 4 groups of people for every m 3. How many groups of people are in the room? 100 m 3 * 4 groups / m 3 = 400 groups.

The units are:

n {mol} = c {mol / m 3} * V {m 3

Note that m 3 can be L, cc, cm 3, ml, m 3 or any other measure of volume.

For the pH value, first determine the concentration of H + in ■■■■■ / L. Then take the negative logarithm. If H + is concentrated in mol / Lc then pH = log (c)

Sorry, I came here late, this is not my best job, but it helps.

What is N in Chemistry?

n = not from

m = in number grams.

M = molecular weight

c = con of the sun.

V = volume Ls

Now sesame is the number of (mock) molecules that are abundant.

If there is no mole, do not drive

Conc They have different units / beds, grams / lights etc.
