Although coals is a complex mixture of substances, its elemntal composition can be approximated by the formula C135H96O9NS. Using this formula calculate the mass of carbon in 1.00 x 10^9 kg of coal
A 12-oz (355-mL) Pepsi contains 38.9 mg caffeine (molar mass ?? 194.2 g/mol). Assume that the Pepsi, mainly water, has a density of 1.01 g/mL.
How would the observed molarity of your experiment be affected by the following circumstances. (i.e. would it be higher than the true value, lwer than the ture vaule or remain unchaged?)
1.What is the effect of the following on the observed melting point of the compound: a) insoluble purity, such as charcoal; b) incomplete drying of the sample; c) less recrystallization solvent was used than it was needed?
