What amount is a mol?
It is the molar mass in grams of a substance.
A weak base that encompasses a concentration of 1.4 mol per litre has a percent ionization of 0.63%. Calculate the Kb of this weak base

You would do well to go to the top of the board, click on "ask a new question" and post separately instead of piggy backing on another problem. Yours is likely to lost this way.
A mole (mol) is a unit used in chemistry to measure the amount of a substance. It is equivalent to Avogadro's number, which is approximately 6.022 x 10^23 particles (atoms, molecules, ions, etc.) per mole.
To calculate the amount in moles, you need to know the number of particles or the mass of the substance. The formula to convert between mass and moles depends on whether you have the molar mass (mass per mole) or the formula of the substance.
If you have the number of particles, you divide the number of particles by Avogadro's number to get the amount in moles.
If you have the mass of the substance, you divide the mass by the molar mass to obtain the amount in moles.
For example, if you have 10 grams of sodium (Na), and the molar mass of sodium is approximately 22.99 grams per mole, you would divide the mass by the molar mass: 10 g / 22.99 g/mol = 0.435 moles.
Conversely, if you have 2 moles of carbon dioxide (CO2), you can multiply the number of moles by Avogadro's number to find the number of particles: 2 mol x 6.022 x 10^23 particles/mol = 1.2044 x 10^24 particles.
