Why is the weight of purified caffeine lower than the weight of crude caffeine?

The purified caffeine weighs less because the impuriries have been removed.

Why do you treat lower API gravity crude to meet product specification?
Lower API crude requires treatment in high temperature and longer retention time to meet proper oil production specification Note - lower API (light crude) is free flowing while higher API (heavy crude) does not flow easily.
Does caffeine lower sperm count?
Caffeine does lower sperm count in some men. Caffeine can help improve the sperm's mobility to reach the egg. For others, it can lead to genetic mutation of the sperm and cause it to have a harder time to penetrate the egg.
What temperature does crude oil evaporate?
Since crude oil contains a variety of hydrocarbon components of different molecular weights, there is no single evaporation temperature. As crude oil is heated the lower molecular weight components boil off first. At temperatures above 650°F the crude oil will begin the process of "cracking" in which the larger components thermally degrade into smaller components. If crude oil is heated in this manner in the absence of oxygen, a final solid product called petroleum coke will be left behind, which consists of carbon, as well as the other impurities in the crude oil that were not removed such as sulfur, vanadium, etc.
Is Folgers Country Roast coffee a regular caffeine coffee?
Coffee can have many different brews, flavors, and roasts. Unless the container specifies that is it decaffeinated or of a lower caffeine content, it has a normal caffeine content.
What is dead crude?
Crude oil comes from the reservoir as live crude, containing methane and other lower carbon compounds that are liberated as the pressure is reduced (in the reservoir, in the well, in the separator or storage battery) and the crude is allowed to cool. Dead crude is degassed crude meaning no more gas is likely to be liberated. The volumetric measurement of crude is normally done at "standard conditions" of atmospheric pressure and 60 degrees F, although standards vary.

What are the relationships between weight and density?
Given an unchanging volume, if you lower the density you will lower the weight, and the revers is true.if you lower the weight the the density would lower as well.This applies to any gravitational field if you are measuring density as a function of weight per volume.
What coffee beans contain less caffeine and are higher quality?
Arabica coffee beans http://en.wikipedia.org/wiki/Coffea_arabica Darker roasted coffees also tend to be lower in caffeine
Can mountiandew lower sperm count?
Caffeine has been found to lower sperm count. The amount of soda needed to be consumed to dramatically lower sperm quality is about 1 liter per day.
Does lemon tea contain caffeine?
Yes, all tea has caffeine, unless you brew with decaffeinated tea.
What is mixed with crude oil from the ground to form kerosene?
Nothing. Kerosene is distilled from crude oil. Different constituents of crude oil have different degrees of volatility, so can be separated by heating them at different temperatures or removing condensations at specific temperatures. For example, gasoline is more volatile, so has a lower vaporization temperature than kerosene and a lower condensation temperature. By removing condensates under controlled conditions in a fractional distilling apparatus, the various parts of crude can be effectively separated in very pure form.
