Question

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

Answer 1

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. 

Answer 2

Answer : The concentration in mol/L is $1.6\times 10^{-4}mol/L$

Explanation : Given,

Moles = $8.00\times 10^{-5}mol$

Volume of solution = 500 mL

Formula used :

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

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

$\text{Concentration}=\frac{8.00\times 10^{-5}mole\times 1000}{500mL}=1.6\times 10^{-4}mol/L$

Therefore, the concentration in mol/L is $1.6\times 10^{-4}mol/L$
