6.02x10^23 is 1 mol. So 4.350/6.02 = .7226
.7226x200.6=144.95
<h3>
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

The pressure increase does not affect the equilibrium shift reaction.
2.02 x 10²³molecules
Explanation:
Given parameters:
Mass of NH₃ = 5.7g
Unknown:
number of molecules = ?
Solution:
To solve this problem, we need to approach it from the mole point of view.
A mole of any substance is the amount that contains the avogadro's number of particles.
We first find the number of molecules in NH₃ and then proceed to find the amount of particles it contains.
Number moles =
Molar mass of NH₃ = 14 + 3(1) = 17g/mole
Number of moles = = 0.34moles
Number of molecules;
1 mole of of NH₃ = 6.02 x 10²³
0.34 moles = 0.34 x 6.02 x 10²³ = 2.02 x 10²³molecules
