The models which shows 6 electrons in the outer shell are Oxygen, Sulfur, Selenium, Tellurium and the radioactive element Polonium
<span>Acetone has a density of 784 kg/mÂł (this you can look up).
This equals 784.000 g/mÂł (kilo means 1000).
Which can be converted to 0.784 g/cm3 (1 m3 is 1.000.000 cm3).
A cm3 is exactly 1 ml. So 0.784 g/cm3 = 0.784 g/ml.
We have 6.68 gram of acetone. 6.68 g / 0.784 g/ml = 8.52 ml.
So the volume of 6.68 grams of acetone is 8.52 ml.</span>
