12cm cubed.
Formula is length x width x height and in this case it would be 2x3x2 which equals 23
The formula of acetic acid is CH3COOH => C2H4O2.
So, the acetic acid has the same number of atoms of carbon (C) than of oxygen (O).
Therefore, the sample that contains 96.5 moles of carbon, will contain also 96.5 moles of O.
Answer: 96.5 moles of oxygen.
<h3><u>Question</u><u>:</u><u>-</u></h3>
In which one element replaces a similar element in a compound?
<h3><u>Answer</u><u>:</u><u>-</u></h3>
A single-replacement reaction
<h3><u>Explanation:</u><u>-</u></h3>
A single-replacement reaction is a reaction in which one element of a compound is replaced by another.
Freezing point depression is a colligative property.
The formula that rules it is:
ΔT f = Kf * m
Where m is the molality of the solution => m = moles of solute / Kg of solvent
=> m = 0.31 mol / 0.175 kg = 1.771 m
And kf = 1.86 °C/m
=> ΔTf = 1.771 m * 1.86 °C / m = 3.3 °C
=> Freezing point of the solution = normal freezing point of water - 3.3 °C = 0 - 3.3°C = - 3.3°C.
Answer: -3.3 °C
