Calculate the mass of sodium acetate (CH3COONa) required to make 500 mL of 0.375 molar aqueous solution. Molar mass of sodium acetate is 82.0245 g mol–1
0.375 M solution of (CH3COONa) = 0.375 moles(grams) of (CH3COONa) dissolved in 1000 ml of solvent.
But according to question ,we have to make a 500 ml solution of (CH3COONa)
∴Number of moles of sodium acetate in 500 mL
Molar mass of sodium acetate = 82.0245 g mole–1 (Given)
∴ Required mass of sodium acetate = (82.0245 g mol–1) (0.1875 mole)
= 15.38 g

Thanks for elaboration
Thanks
thanks for such good explanation
Supriti try to love
thnx
thanx
Why we multi. 82.0245 with 0.1875 not divede
Thank you but I want it a little more briefly
Please tell more about the concept
How 100 ml????
