Question

The molar mass of kcl is 74.55 g/mol. if 8.45 g kcl are dissolved in 0.750 l of solution, what is the molarity of the solution? use molarity equals startfraction moles of solute over liters of solution endfraction.. 0.113 m 0.151 m 6.62 m 11.3 m

Answer 1

Answer: 0.151 M

Step-by-step explanation:

We first need to convert the amount of KCl into moles. This is 8.45/74.55 = 0.113 moles.

So, the molarity is 0.113/0.750 = 0.151 M
