A chemist prepares a solution of silver(II) oxide (AgO) by measuring out 0.00089 umol of silver(II) oxide into a 250 mL volumetric flask and filling the flask to the mark with water.
Calculate the concentration in  of the chemist's silver(II) oxide solution.

To calculate the concentration of the silver(II) oxide (AgO) solution, we can follow these steps:

### Step 1: Convert micromoles (μmol) to moles
The amount of silver(II) oxide (AgO) is given as 0.00089 μmol. Since 1 μmol = \(1 \times 10^{-6}\) moles, we can convert this to moles:

\[
\text{Moles of AgO} = 0.00089 \, \mu mol \times 10^{-6} \, mol/\mu mol = 8.9 \times 10^{-10} \, mol
\]

### Step 2: Convert the volume from milliliters to liters
The volume of the solution is 250 mL. Since 1 L = 1000 mL, we convert the volume to liters:

\[
\text{Volume of solution} = \frac{250}{1000} = 0.250 \, L
\]

### Step 3: Calculate the concentration
The concentration of a solution is given by the formula:

\[
\text{Concentration (M)} = \frac{\text{moles of solute}}{\text{volume of solution in liters}}
\]

Substitute the values we found:

\[
\text{Concentration of AgO} = \frac{8.9 \times 10^{-10} \, mol}{0.250 \, L} = 3.56 \times 10^{-9} \, M
\]

Thus, the concentration of the chemist's silver(II) oxide solution is:

\[
\boxed{3.56 \times 10^{-9} \, M}
\]
