In an experiment, nitrogen gas was composed "over water" when sulfuric acid solution was mixed with a sodium nitrite solution. 0.02mol of nitrogen gas were collected at 0.25 atm at a temperature of 21C (294.15K). Determined the R value from this. I now require to compare my R value against the accepted R value. Explain what the accepted R value is?
