# What is the concentration of all ions present in the following solutions: 0.100 mole of Ca(NO_3)_2 in 100.0 mL solution?

$3.00 M$

#### Explanation:

Here's our concentration for multiplying the solvated ions by.

$\frac{.100 m o l}{.1000 L} = 1.00 M$

$C a {\left(N {O}_{3}\right)}_{2}$ is an ionic compound, thus it will completely dissolve in solution. Therefore,

$C {a}^{2 +}$ and $2 N {O}_{3}^{-}$ will form.

$C {a}^{2 +}$: $1 \cdot 1 = 1.00 M$
$2 N {O}_{3}^{-}$: $2 \cdot 1 = 2.00 M$

Summing all of these ions would give $3.00 M$.
