What is the molarity of 61.7 g LiCl in 250.0 mL of solution?

Answer 1

Molarity = moles of solute/Liters of solution ( 250.0 ml = 0.250 liters )

Find moles.

61.7 grams LiCl (1 mole/42.391 grams)

= 1.455 moles lithium chloride

Molarity = 1.455 moles LiCl/0.250 liters

= 5.82 M LiCl

Answer 2

To find the molarity, first calculate the number of moles of LiCl in 61.7 g using the molar mass of LiCl (42.39 g/mol). Then, divide the moles of LiCl by the volume of the solution in liters (0.250 L) to get the molarity.
