Solid sodium hydrogen carbonate, NaHCO3, decomposes on heating according to the equation: 2 NaHCO3(s) <--> Na2CO3(s) + H2O(g) + CO2(g) A sample of 1.00 x 102 grams of solid NaHCO3 was placed in a previously evacuated rigid 5.00-liter container and heated to 160 0C. Some of the original solid remained and the total pressure in the container was 7.76 atmospheres when equilibrium was reached. Calculate the number of moles of H2O(g) present at equilibrium. How many grams of the...
