Question

What is the molar concentration of a solution that contains 2.4 mol in 175 mL solution?

Answer 1

`M=13.7(mol)/(L)=13.7M`

Step-by-step explanation:

Hello,

In this case, we define the molar concentration or widely known as molarity as the ratio of the moles of the solute to the volume of the solution in litres. Thus, for the computation of the molar concentration we make sure we have litres:

`V_(solution)=175mL*(1L)/(1000mL) =0.175L`

Next, we can compute the molarity in mole per litre or just molar units by:

`M=(n_(solute))/(V_(solution)) =(2.4mol)/(0.175L) \\\\M=13.7(mol)/(L)=13.7M`

Best regards.

Answer 2

`M = 13.714\,(mol)/(L)`

Step-by-step explanation:

The molarity is the ratio of moles solute to volume of solution. Then,

`M = (2.4\,mol)/(\left(175\,mL\right)\cdot \left((1)/(1000)\,(L)/(mL) \right))`

`M = 13.714\,(mol)/(L)`
