The consumption of red wine induces headaches in some subjects who can drink other alcoholic beverages without suffering. The cause for this effect has been attributed to a number of components, often the high level of phenolics in red wine, but a mechanism has been elusive. Some alcohol consum...
The molar mass, or sometimes called atomic mass or molecular weight, is defined to be the mass of a particular element or compound over 1 mole of the substance. It can be obtained from this definition or by taking the sum of the mass of atoms composing a compound. Molar mass is ...
Calculate the volume of one mole of aluminum. Pure aluminum metal has a density of 2.70 g/cm^3. Calculate the volume of 25.2 g of pure aluminum. Calculate the volume of a 7.85 kg aluminum block if the density of aluminum is 2.70g/cm^3. The average ma...
Consider a mixture of several gases of identical masses. Will all the mass fractions be identical? How about the mole fractions? Why do real gases deviate from Boyle's law? If you put an effervescent tablet of vitamin C in water, carbonic gas is liberated . Describe an experiment that allo...
