An example would be iodine has a lower relative atomic mass than tellurium, so it should come before tellurium in Mendeleev's table. In order to get iodine in the same group as the other elements with similar properties such as fluorine, chlorine, and bromine, he had to put it after tellurium, which broke his own rules.
From the density of ethanol given, the number of pounds of ethanol in the drum will be 46.099 pounds.
<h3>How to calculate density</h3>
Density of ethanol = 0.789/cm³
1 gallon = 3785.4ml
Volume of ethanol = 7 gallons = 7 × 3785.4ml = 26497.8ml
Mass of ethanol = Volume × Density.
= 26497.8 × 0.789
= 20906.764g
Since 1g = 0.002205 pounds, the mass of ethanol will be:
= 20906.764 × 0.002205
= 46.099 pounds.
