Answer:</h3>
0.112 deciliter
<h3>
Explanation:</h3>
- Molarity of a solution shows the amount of solute in moles contained in a liter of solution.
- Therefore; Molarity = Number of moles ÷ Volume of solvent in liters
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
<h3>Step 1: Determine the number of moles of LiF</h3>
Moles = Mass ÷ Molar mass
= 0.255 g ÷ 25.94 g/mol
= 0.00983 mole
<h3>Step 2: Determine the volume of LiF</h3>
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
