How would you prepare 2.5 l of a 0.800m solution of kno3?

First  find the mass of solute:

Molar mass KNO₃ = 101.1032 g/mol

mass =  Molarity * molar mass * volume

mass = 0.800 * 101.1032 * 2.5

mass = 202.2064 g of KNO₃

To prepare 2.5 L (0800 M) of KNO3 solution, must weigh 202.2064 g of salt, dissolve in a Beker, transfer with the help of a funnel of transfer to a volumetric flask, complete with water up to the mark, capping the balloon and finally shake the solution to mix.

hope this helps!

Woah that’s a lot to read xd i’ll try though. i’ll get back t you if. i know the andwer
