Answer : The molarity of a solution is, 0.0337 M
Explanation : Given,
Mass of
= 468 mg = 0.468 g (1 mg = 0.001 g)
Volume of solution = 50.0 mL
Molar mass of
= 278 g/mole
Molarity : It is defined as the number of moles of solute present in one liter of volume of solution.
Formula used :
![\text{Molarity}=\frac{\text{Mass of }MgI_2\times 1000}{\text{Molar mass of }MgI_2\times \text{Volume of solution (in mL)}}](https://tex.z-dn.net/?f=%5Ctext%7BMolarity%7D%3D%5Cfrac%7B%5Ctext%7BMass%20of%20%7DMgI_2%5Ctimes%201000%7D%7B%5Ctext%7BMolar%20mass%20of%20%7DMgI_2%5Ctimes%20%5Ctext%7BVolume%20of%20solution%20%28in%20mL%29%7D%7D)
Now put all the given values in this formula, we get:
![\text{Molarity}=\frac{0.468g\times 1000}{278g/mole\times 50.0mL}=0.0337mole/L=0.0337M](https://tex.z-dn.net/?f=%5Ctext%7BMolarity%7D%3D%5Cfrac%7B0.468g%5Ctimes%201000%7D%7B278g%2Fmole%5Ctimes%2050.0mL%7D%3D0.0337mole%2FL%3D0.0337M)
Therefore, the molarity of a solution is, 0.0337 M
