What is the mass of koh found in a 785 ml of a 1.43 m solution of koh

Molarity is defined as the ratio of number of moles to the volume of solution in litres.

The mathematical expression is given as:

Here, molarity is equal to 1.43 M and volume is equal to 785 mL.

Convert mL into L

As, 1 mL = 0.001 L

Thus, volume = = 0.785 L

Rearrange the formula of molarity in terms of number of moles:

n =

= 1.12255 mole

Now,  Number of moles  =

Molar mass of potassium hydroxide  = 56.10 g/mol

1.12255 mole  =

mass in g =

= 62.97 g

Hence, mass of = 62.97 g
