Question

help me in this one frdzz

Answer 1

HOLA MATE !!!

HOPE THIS HELPS YOU...

Given Data:

Total volume of the solution ,v = 2L=2000mL

Mass of solute = 20g  

Total mass of solute,m = molar mass of solute * mass of solute                   =342*20                                                                                                              =6840g /mol

Formula:

Molarity [M] = Total mass of solute/Total volume of the solution = m/v

Step-by-Step Explanation :

=> M = m/v

=> M = 6840/2000

=> M = 3.42 mol/L

Hence , the concentration of the solution is 3.42mol/L

THANK YOU FOR THE WONDERFUL QUESTION...
