<span>Some solutions demonstrate colligative properties, which rely on the quantity of solute in a solvent. To find the elevation in boiling point, we use the formula:
</span><span>ΔT(boiling point) =
(Kb)mi
where Kb represents a constant, m is the solution's molality, and i is the van't Hoff factor.
From the provided information, we can easily determine i as follows:
</span>ΔT(boiling point) = (Kb)mi
103.45 - 100 = (0.512)3.90i
i = 1.73 <-------van't Hoff factor
Answer:
6
Explanation:
H6 indicates the presence of helium atoms, with 6 representing their quantity.
Assuming the edge length of the cube is m.
Since the cube's sides are all equal, you can find its volume using the formula:
volume of cube = m^3
Now, using the provided edge length:
volume = (4.33)^3 = 81.1827 cm^3
According to unit conversion standards, 1 cm^3 = 0.001 liters.
So:
volume of cube = 81.1827 cm^3 = 0.0811827 liters
The production yield is expected to be 44.55.
Each molecule contains two of these ions
1 mole corresponds to 6.02 * 10^23 entities.
1 mole of (NH4)2S contains 2*6.02 * 10^23 ammonium ions (NH4+ in this instance) = 1.204 * 10^24 ammonium ions
5 moles of (NH4)2S accounts for 5 * 1.204*10^24 =
6.02 * 10^24 moles of NH4+ ions <<<<====Result
