@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 11.96 g of kaolinite?

@X@user.full_name@X@ @GMU: The density of a particular gas is 0.6733 g/L at 734.81 mm Hg and 24.85 °C. What is the molecular mass of the gas?

Body Temperature and Pressure Saturated (BTPS) means

Given 950 ml of dry gas at 24oC and a barometric pressure of 1 atmosphere, what volume would the gas occupy at BTPS? STPD?

@X@user.full_name@X@ @GMU: What must the reaction quotient Q be, if the free energy is -284.620 kJ at 25.0oC?C2H2(g) + 2 H2(g) → C2H6(g) ΔGo = -242.202 kJ.

If 5 liters of oxygen in a container at 740 mmHg is compressed to 2 liters, what is the new pressure inside the bag?
