Answer:
1.070MKCl
Step-by-step explanation:
So we know that the original formula is M= n/L (n being moles of solute, L being liters of solvent)
Since we do not have liters in this problem, we would need to convert milliliters to liters
213 mL= 0.213 L
We then see that we do not have moles, but we do have a mass, being 17.0 g. we would need to convert these grams to moles, giving us 0.228 mol.
Then, you would plug in 0.228 for your n, and now you are ready to solve your original formula, plugging everything in.
M=n/L
M=0.228 mol/0.213L
M= 1.070MKCl
I know this was long, but I hope this helps (:
