## What is 0.05 molar KOH?

pH of a 0.05 M KOH solution is 12.7.

## How do you calculate molar mass quizlet?

The molar mass of a compound can be calculated by adding the standard atomic masses (in g/mol) of the constituent atoms. Gram atomic mass is the mass, in grams, of one mole of atoms in a monatomic chemical element. It is numerically equal to the relative atomic mass (or atomic weight) in grams.

## How do you solve for moles?

The unit is denoted by mol.
1. The formula for the number of moles formula is expressed as.
2. Given.
3. Number of moles formula is.
4. Number of moles = Mass of substance / Mass of one mole.
5. Number of moles = 95 / 86.94.

## What is molar mass?

Description. Molar mass M is the mass of a chemical compound divided by its amount-of-substance measured in moles. It is defined as MB = m/nB, where m is the total mass of a sample of pure substance and nB is the amount of substance B given in moles. The definition applies to pure substance.

## What is the unit of KOH?

Hence, the molecular weight of KOH is. 105 u .

## What is 0.002 M of KOH?

(iv) 0.002 M KOH: Hence, the pH of the solution is 11.31.

## What does KOH measure?

A KOH examination is a straightforward, simple procedure that your doctor might order to determine whether you have a fungal infection on your skin. It's a low-risk procedure, though you may experience some light bleeding in the area where your skin was scraped for the cell sample.

## What is a solution of KOH?

Potassium hydroxide solution (KOH aqueous) is a colourless inorganic liquid that acts as a strong base (alkali). KOH solution is also known as caustic potash or potash lye and has many different applications. During the KOH liquid production process, chlorine and hydrogen are formed as co-products.

## What is 0.001 N KOH solution?

0.001 N KOH solution has a pH of 11.

## What does a 0.01 M solution mean?

An acid has a molarity of 0.01M means that the molar concentration of the acid is 0.01M. To put it very simply, let us consider that the molecular weight of the acid is X. Now, if X gm of the acid is added to a solvent to make a final solution of 1ltr, the solution will have a concentration of 1M.
