grams of oxygen gas = 0.01875 moles * (16.00 grams/mole) grams of oxygen gas = 0.3 grams It should be fairly obvious that you could have plugged in the mole fraction right away in this particular example because only one type of atom was present on both sides of the equation. However, ...
Unlike molarity and molality which are expressed in terms of solute per amount of solution or solvent, mole fraction can be used to express the amount of solute per amount of solvent or vice versa. For mole fraction of solute, it is obtained by dividing the moles of the solute by t...

a solution. The property which helps sugar molecules to dissolve is known assolubility. Hence, the term solubility can be defined as a property of a substance (solute) to dissolve in a givensolvent. Asoluteis any substance which can be either solid or liquid or gas dissolved in a solvent....

Sodium is a chemical element with symbol Na and atomic number 11. Know the atomic mass of sodium, sodium atomic number, chemical properties of sodium and more.
CH4 is the second most important anthropogenic greenhouse gas, after CO2, and is directly responsible for approximately 20% of the human-induced greenhouse effect. Year-to-year variations in the atmospheric CH4 growth rate have been puzzling, but show significant correlation with climatic drivers. Th...
Properties of Sodium Phosphate:Sodium phosphate is an ionic compound that contains sodium and phosphate ions in the corresponding crystal structure. According to the electroneutrality principle, each formula unit of sodium phosphate contains three sodium and one phosphate ion. S...
Evolution leaves an imprint in species through genetic change. At the molecular level, evolutionary changes can be explored by studying ratios of nucleotide substitutions. The interplay among molecular evolution, derived phenotypes, and ecological ranges
Learn more about the new definition of the kilogram. It is interesting to note that the definition of some SI units has improved over time. For example, consider the historical changes to the definition of one second: 1874 - 1956: 1/(86,400) of a day 1956 - 1967: The fraction 1/(...
