Distilled water and sealed container are in equilibrium when these objects do not exchange more heat.

<h3>What is thermal equilibrium?</h3>

The expression 'thermal equilibrium' makes references to the phenomenon by which two objects interact with each other to exchange heat energy.

Objects in contact can transfer heat to reach a thermal equilibrium state where the temperature is the same for both objects.

In conclusion, distilled water and sealed container are in equilibrium when these objects do not exchange more heat.

What is the molarity (M) of an 85.0-mL solution (total volume) containing 1.77 g of ethanol (C2H5OH)
Liono4ka [1.6K]

Answer: The molarity of solution is 0.453 M

Explanation:

Molarity of a solution is defined as the number of moles of solute dissolved per liter of the solution.

Molarity=\frac{n\times 1000}{V_s}

where,

n = moles of solute

V_s = volume of solution in ml

moles of C_2H_5OH = \frac{\text {given mass}}{\text {Molar mass}}=\frac{1.77g}{46g/mol}=0.0385mol

Now put all the given values in the formula of molality, we get

Molarity=\frac{0.0385\times 1000}{85.0}

Molarity=0.453

Therefore, the molarity of solution is 0.453 M

Papessa [141]

Answer:

Most people, including chemists, prefer to use these common names for the compounds mentioned because they are frequently found, and the common names are shorter, easier to pronounce, and more widely known.
