Calculate the amount (g) of each of the following salts that need to be added to a 200 mL volumetric flask to produce a 2 M solution of S.




Dr. BOB222,

Could you please check the following?
Thank you.

CaSO4: moles x atomic mass = .0400 x 32.066 amu = 12.8264 g
12.8264 gS x molar mass CaSO4/atomic mass S =
12.8264 g x 136.1416/32.066 =

54.45664 g

(NH4)2SO4: 12.8264 x 132.1402/32.066 (molar mass(NH4)2SO4/atomic mass S)= 52.85608 g

Fe2(SO4)3: 12.8264 x 399.8801/32.066
(molar mass Fe2(SO4)3/atomic mass S)=
159.95204 g

Thank you again.
