@X@user.full_name@X@ @GMU: Kaolinite, a clay mineral with the formula Al4Si4O10(OH)8, is produced naturally by the chemical weathering of aluminum silicate minerals like feldspar (granite). Kaolinite is used industrially as filler in slick-paper for magazines and as a raw material for ceramics. How many grams of oxygen are present in 10.00 g of kaolinite?

@X@user.full_name@X@ @GMU: Assume you have an open ended manometer filled with an oil having a density of 0.7901 g/mL at 20°C rather than mercury (density = 13.546 g/mL at 20°C). What is the pressure in atmospheres if the level of the arm open to the atmosphere is 126.82 cm lower than the level in the arm connected to the gas sample? The atmospheric pressure reading is 756.62 mm Hg.
