Question

8.00*10^-5 mol was diluted to 500ml what is the concentration in Mol/L?

Answer 1

Answer : The concentration in mol/L is
`1.6* 10^(-4)mol/L`

Explanation : Given,

Moles =
`8.00* 10^(-5)mol`

Volume of solution = 500 mL

Formula used :

`\text{Concentration}=\frac{\text{Moles of solute}* 1000}{\text{Volume of solution (in mL)}}`

Now put all the given values in this formula, we get:

`\text{Concentration}=(8.00* 10^(-5)mole* 1000)/(500mL)=1.6* 10^(-4)mol/L`

Therefore, the concentration in mol/L is
`1.6* 10^(-4)mol/L`

Answer 2

Make sure all units are consistent. Convert ml to L first. (500ml = 0.5L). Then divide the mole by the volume which would result to 1.6*10^-4mol/L. This can also be expressed as interms of molarity (M). 1 M = 1 mol/L hence the final answer is 1.6*10^-4 M.
