a sample of N2O3(g) has a pressure of 0.019atm. the temperature(in K) is then double and the N2O3 undergoes complete decompositopn to NO2(g) and NO(g). what is the total pressure of the gases

HCLO3 is a colorless, corrosive liquid. At 25 C its density is 4.63 g/mL. A chemist needs 125. g of this acid for a reaction, but often it is safer and more convenient to measure reactive liquids by volume with a graduated cylinder instead of attempting to weigh them on a balance. Calculate the...
