VikaD [51]

Answer:

The concentration of nitrate ion NO_{3}^{-}  is 0.033 M.

Explanation:

Al(NO_{3})_{3} \rightarrow Al^{3+} + NO_{3}^{-}

1 mole of [Al^{3+}]  = 3 mole NO_{3}^{-}

Let  [NO_{3}^{-}]  = 3y

then according to above reaction,

[Al^{3+}] = y

[NO_{3}^{-}] = 0.10 M (given)

[Al^{3+}] = ?

3y = 0.10 M

y = \frac{0.1}{3}

y = 0.033 M

So ,concentration of [Al^{3+}] = y = 0.033 M
