First, determine the amount of substance in moles by dividing the given amount in grams by the molar mass.
17.8 grams LiF x (1 mole / 25.94 grams LiF) = 0.686 moles LiF
Divide this amount of substance by the volume of the solution in liters.
molarity = 0.686 moles LiF / 0.915 L sol'n
The molarity is therefore, 0.75 M.
Answer:
The answer to your question is ∆Hrxm= – 23.9 kJ
The density : 21.63 g/L
<h3>Further explanation</h3>
The gas equation can be written
where
P = pressure, atm
V = volume, liter
n = number of moles
R = gas constant = 0.08206 L.atm / mol K
T = temperature, Kelvin
T = 65+273=338 K
P=2.36 atm
MW Iodine gas (I₂)=254
The density :
