Antacids, such as alka-seltzer, use the reaction of sodium bicarbonate with citric acid in water solution to produce a fizz as follows: 3nahco3 + c6h8o7 → 3co2 + 3h2o + na3c6h5o7 if 4.11 g of the citric acid (c6h8o7, mw = 192 g/mol) react with excess sodium bicarbonate (nahco3), how many grams of carbon dioxide (co2, mw = 44 g/mol) are formed as the solution fizzes?

The size (radius) of an oxygen molecule is about 2.0 ×10−10m. make a rough estimate of the pressure at which the finite volume of the molecules should cause noticeable deviations from ideal-gas behavior at ordinary temperatures (t= 300k ). assume that deviatons would be noticeable when volume of the gas per molecule equals the volume of the molecule itself.
