How many deciliter a of a .88m lif solution be made using 25.5 cg lif? lif molar mass = 25.94 g/mol

0.112 deciliter

In this case we are given;

Molarity of LiF as 0.88 M

Mass of LiF as 25.5 cg

but, 1 g = 100 cg

Therefore, mass of LiF = 0.255 g

Molar mass of LiF = 25.94 g/mol

We are required to calculate the volume of LiF in deciliter

Moles = Mass ÷ Molar mass

          = 0.255 g ÷ 25.94 g/mol

          = 0.00983 mole

Molarity = Moles ÷ Volume

Rearranging the formula;

Volume = Moles ÷ Molarity

Volume of LiF = 0.00983 mole ÷ 0.88 moles/liter

                        = 0.0112 L

But, 1 L = 10 DL

Therefore, Volume = 0.112 DL

Thus, the volume of LiF is 0.112 deciliter
