Question #af319

Answer 1

`M`Cd = `8.90*10^5`

Explanation:

Molarity is defined as `M`= `(mols)/(1L solution)`

First step is to convert .010mg of Cd into mols

.010mg Cd `(1mol Cd)/(112.41gCd)`= `8.90*10^-5` mol Cd

plug this into our Molarity equation

`M`= `(8.90*10^-5)/(1L solution)`

`M`Cd = `8.90*10^5`
