1. The hydrogen density of a mixture of methane, propane, oxygen and ozone is 18.4. Burning of 25 ml of this mixture produces 16 ml of a mixture of carbon dioxide with oxygen measured in the same conditions. The hydrogen density of this mixture increased to 19.75.
Calculate the parts by volume of the components of the initial gas mixture.
2. If one adds to the sodium carbonate solution the nitric acid solution at continuous stirring, 11.88 g of salt mixture can be extracted from the solution obtained. In contrary, if one changes the order of mixing the initial solutions, then 11.26 g of salt mixture can be extracted.
Calculate the masses of the substances in the initial solutions. (Please find two ways of finding the solution).
3. The mass part of nitrogen in the mixture
