3.50 g of an unknown base is dissolved in 289 ml of water and has a concentration of 0.219 m. what is the the identification of the unknown base.

The unknown base should be KOH whose molar mass is 56 g per mol (Answer)

Explanation:

Molarity = moles /(Volume in liters)  

So,  

Moles = Molarity Volume

Molar mass = mass/moles

The unknown base should be KOH whose molar mass is 56 g per mol (Answer)

in chemistry, a solution’s concentration is how much of a dissolvable substance, known as a solute, is mixed with another substance, called the solvent. the standard formula is c = m/v, where c is the concentration, m is the mass of the solute dissolved, and v is the total volume
