Describe how to prepare a 500cm3 solution of 0.2moldm-3 sodium trioxocarbonate(iv)

Question

Give the Apparatus,Method, Theory, Conclusion and precautions.

Answer 1

You want a book?
How many mols do you need? That's moldm-3 x dm^3 = ?
Then mol = g/molar mass. YOu know molar mass and mols, solve for grams, add that amount to a 500 cm3 volumetric flask, dissolve, mix thoroughly, stopper. I don't think you have named sodium carbonate properly. The IUPAC name for Na2CO3 is sodium carbonate.
