  Introduction The high upsurge of incarceration in the USA due to the drug war has negatively impacted the black communities. Blacks are 5-7 times are likely to be charged in court with offenses associated with the drug than whites (Rosenberg et al., 2017). As a result, there is racial bias in the judicial system, encompassing judicial policies, sentence length, arrest rates, convictions, police practices, mandatory minimum sentences, community supervision, diversionary opportunities, and media trends. Therefore, understanding this racial bias would enable relevant policymakers to develop measures to reduce or eradicate this vice and embrace equal treatment of all races in the USA. This portfolio explores the key concepts and socio-historical background of racial bias in the U.S. judicial system. Moreover, the portfolio presents statistical (quantitative) and qualitative findings related to racial bias in U.S. criminal justice. The portfolio also incorporates a case study to dem...

In chemistry, substances consist of large particles. As a result, the best way of expressing these particles is through a unit called a “mole." Therefore, a mole represents the amount of these particles in chemical substances such as chemical elements and molecules. For instance, a specific gram of a chemical element can contain many atoms. A mole is described as the quantity of a chemical substance with 6.02214076*10 23 discrete entities as the number of atoms present in 12 C, which weighs 12g. This number represents Avogadro's constant (N A ). Particles represented in a mole encompass molecules, polyatomic/monoatomic ions, atoms, electrons, etcetera.  The Avogadro's constant is considered "per mole" in chemistry and rounded off to 6.022*10 23 /mol. For this reason, one mole of a specific element comprises the same amount of atoms as represented in one mole of another element. However, a mole of distinctive elements contains different masses since specific atom...
