Answer: protons, neutrons, and electrons. That's how they are compressed.
The answer is D - zinc sulphate and hydrogen
I found the grams per mole values based off of the atomic mass of iodine and Magnesium
Answer:
Explanation:
<u>1) Data:</u>
a) Solute: acetone
b) Solvent: benzene
c) n (solute) = 0.863 mol
d) mass of solvent = 500 g = 0.500 Kg
e) ΔTf = 8.84 °C
f) Kf = ?
<u>2) Formulae:</u>
- Depression of freezing point: ΔTf = m . Kf
- Molality: m = n (solute) / kg solvent
<u>3) Solution:</u>
a) m = 0.863 mol / 0.500 kg = 1.726 m
b) Kf = ΔTf / m = 8.84°C / 1.726 m = 5.12 °C/m ← answer
