We have that the the molarity of methanol in the solution is mathematically given as
Morality=7.91mol/l
<h3>Chemical Reaction</h3>Question Parameters:
An <u>aqueous </u><em>solution </em>of methanol (MM = 32.04 g/mol)
A molality of 8.83 m and a density of 1.15 g/mL.
Generally the equation for the is mathematically given as
where
Mass of solution=(100+282.2)
Mass of solution=1289.9
Volume=1289.9/1.15
Volume=1.115L
Therefore
Morality=8.83/1.115
Morality=7.91mol/l

Answer:
Final temperature of water is
Explanation:
1 mol of LiBr releases 48.83 kJ of heat upon dissolution in water.
So, 2 moles of LiBr release or 97.66 kJ of heat upon dissolution in water.
This amount of heat is consumed by 1000.0 g of water. Hence temperature of water will increase.
Let's say final temperature of water is .
So, change in temperature () of water is
or (t-25) K
Heat capacity (C) of water is
Hence,
where m is mass
So,
or,
Hence final temperature of water is
