Question

What is the molarity of a solution containing 56 grams of LiF in 959 mL of solution?
O 1.5 M
O 4.4 M
O 0.0022 M
O 22 M

Answer 1

Answer:

2.25 M     <========= I do not see this in your selection of answers !

Explanation:

Mole weight of  Li F

      ( from periodic table ) = 6.94 + 18.998  = 25.938 gm/mole

56 gm / ( 25.938 gm /mole) = 2.15899 moles

2.15899 mole / (.959) L = 2.25 M
