Answer:
(β⁺), and another one is 01e
A solution is a homogeneous type of mixture of two or more substances. A solution has two parts: a solute and a solvent.
Answer:
0.805 M.
Explanation:
Hello!
In this case, since the molarity of a solution is computing by dividing the moles of solute over the volume of solution in liters (M=n/V), for 15.0 g of potassium chloride (74.55 g/mol) we compute the corresponding moles:
![n=15.0gKCl*\frac{1molKCl}{74.55gKCl}=0.201molKCl](https://tex.z-dn.net/?f=n%3D15.0gKCl%2A%5Cfrac%7B1molKCl%7D%7B74.55gKCl%7D%3D0.201molKCl)
Next, since the volume is 0.2500 in liters, the molarity turns out:
![M=\frac{0.201mol}{0.2500L} \\\\M=0.805M](https://tex.z-dn.net/?f=M%3D%5Cfrac%7B0.201mol%7D%7B0.2500L%7D%20%5C%5C%5C%5CM%3D0.805M)
Best regards!
