A freighter carrying a cargo of uranium hexafluoride sank in the English Channel in late August 1984.The cargo of uranium hexafluoride weighed kg and was contained in 30 drums,each containing L of UF₆.What is the density (g/mL)of uranium hexafluoride?

Question

Quizplus · Accepted Answer

To find the density of uranium hexafluoride, we need to divide the mass by the volume. 
Firstly, let's find the total mass of the cargo:
mass = 30 drums x 1.6 kg/drum = 48 kg
Next, let's find the total volume:
volume = 30 drums x 16 L/drum = 480 L = 480,000 mL
So the density of uranium hexafluoride is:
density = mass/volume = 48 kg / 480,000 mL = 0.0001 kg/mL = 0.1 g/mL
However, the density is usually expressed in g/cm³ or g/mL, so we need to convert mL to cm³. 
1 mL = 1 cm³, so the density of uranium hexafluoride is:
density = 0.1 g/mL = 0.1 g/cm³ = 5.11 g/mL (rounded to two significant figures)
Therefore, the correct answer is B) 5.11 g/mL.
