Hint: $\left[ Cr{{\left( {{H}_{2}}O \right)}_{4}}C{{l}_{2}} \right]$ is a coordination compound. Here the overall charge on the compound is +1. We can calculate the number of moles by the formula:\[Number\text{ }of\text{ }moles=Volume\times Molarity\]
Formula used: \[Number\text{ }of\text{ }moles=Volume\times Molarity\]
Complete step by step answer:
- We can write the formula of given compound as $\left[ Cr{{\left( {{H}_{2}}O \right)}_{4}}C{{l}_{2}} \right]$. Now, we will first find the charge on the compound. We know that charge on chromium is +3, charge on water is zero, charge on chlorine is -1. So, we get the overall charge on the compound as:
\[\begin{align}
& ch\arg e=3+0\times \left( 4 \right)+2\times \left( -1 \right) \\
& =+1 \\
\end{align}\]
So, we can see that the overall charge present is +1. Therefore, there will be one chloride ion required.
- We can say that if one mole of a complex is present then one mole chloride ion will be available to form AgCl. In simple words we can say that 1 mole of complex will give 1 mole of AgCl.
- Now let’s calculate the number of moles, we can use the formula:
\[Number\text{ }of\text{ }moles = Volume\times Molarity\]
-We are being provided with the volume and molarity, we should first convert the volume given in ml into litres. So,100 ml = 0.1 l
-So, we will put the values in the equation,
\[\begin{align}
& Number\text{ }of\text{ }moles=0.1\times 0.01 \\
& =0.001\text{ }moles \\
\end{align}\]
Hence, we can conclude that the correct option is (A), that is the number of moles of AgCl precipitated would be 0.001 moles.
Note: Here, we are being provided with a 0.01 M solution, that is M is the molarity of the solution. One should not be confused in units’ M and m. M is the unit of molarity and m is the unit of molality.
