How do you go from mol to L?
Converting from moles to volume (liters): Multiply your mole value by the molar volume constant, 22.4L. Converting from particles (atoms, molecules, or formula units) to moles: Divide your particle value by Avogadro’s number, 6.02×1023.
How do you convert mol g to mol?
Divide the number of grams of the compound, NaOH, by the molecular weight and as a result, the grams (g) unit cancels and all we have left is the unit mol (moles).
Can you use moles in the Henderson Hasselbalch equation?
We can determine the moles of acetic acid by using M = mol/L, which gives us mol = ML = (2M) * (0.5L) = 1mol acetic acid. If we use the Hendersen Hasselbach equation we can see that the pH equals the pKa when the concentration of conjugate base (acetate) equals the concentration of acid.
How do you use Henderson Hasselbalch equation to find concentration?
The formula for the Henderson–Hasselbalch equation is: pH=pKa+log([A−][HA]) pH = p K a + log ( [ A − ] [ HA ] ) , where pH is the concentration of [H+], pKa is the acid dissociation constant, and [A–] and [HA] are concentrations of the conjugate base and starting acid.
Can you convert grams to liters?
To convert a gram measurement to a liter measurement, divide the weight by 1,000 times the density of the ingredient or material. Thus, the weight in liters is equal to the grams divided by 1,000 times the density of the ingredient or material.
How do you find moles from liters and molarity?
To calculate the number of moles in a solution given the molarity, we multiply the molarity by total volume of the solution in liters.
What is the formula to convert moles to grams?
One mole consists of Avogadro number of atoms. If you know the quantity of mole, it can be converted into grams and vice versa….= 3 x 28.01 = 84.03 grams.

What pKa do you use in the Henderson-Hasselbalch equation?
4.74
Thinking about the Henderson-Hasselbalch equation, once again, the pKa is equal to 4.74, and we need to think about the ratio of the concentration of the acetate anion to the concentration of acetic acid. For this example, the concentration of the acetate anion is greater than the concentration of acetic acid.
Which pKa value would you use in the Henderson-Hasselbalch equation?
You must use pKa2 .
What is the Henderson Hasselbalch equation explain?
The Henderson Hasselbalch equation is an approximate equation that shows the relationship between the pH or pOH of a solution and the pKa or pKb and the ratio of the concentrations of the dissociated chemical species. In order to use the equation, the acid dissociation constant must be known.
What is the mass of 1 mole of hydrogen gas?
This equates to roughly 6.02×1023, also referred to as Avogadro’s Number. So, 1 mole of hydrogen gas (H2) contains 6.02x1023molecules, and 1 mole of glucose (C6H12O6.) also contains 6.02x1023molecules, but as H2is a much simpler molecule, 1 mole of H2will have a much smaller mass (the molar mass) than 1 mole of C6H12O6.
How do you convert grams to moles in chemistry?
– Grams to moles formula To correctly estimate the number of moles, n , of a substance of a specific mass, m , (in grams), you need to follow the grams to moles formula: n = m / M ,
What is the difference between molar mass and g mol?
The most common units used are g/ml or g/l. Remember that 1 liter is equal to 1 cubic decimeter. Molar mass is the mass of 1 mole of the solute. It is expressed in grams per mole. It is a constant property of each substance – for example, the molar mass of water is approximately equal to 18 g/mol.
How do you calculate molarity in chemistry?
Molarity refers to the molar concentration of a solution, that is, the number of moles of solute dissolved in 1 liter of solution, as mol/L, abbreviated as M. Molarity Calculator Equation: Molarity = Mass / (Volume × Molar Mass); Mole = Concentration (g/L) × Volume (L) / MW (g/mol); Molarity Calculation Example:
