Scientific method experiment - Essay Example56)To establish this, the experimentalist used quadruplet samples of five gasolinees namely atomic number 8, Hydrogen, Carbon Dioxide and Sulfur Hexafluoride. He used other tools such as quartette testing tubes, a top- loading balance and a syringe. The experimentalist measured a volume of 50ml of each of the gas samples. By using the syringe and the balance, the experimentalist calculated the saddles of each of the 50ml-sample. He observed that although the samples were of the same size, they weighed different. The vacuum weighed 0.00g Oxygen 0.54g, Hydrogen 0.11gm , Carbon Dioxide .088g and Sulfur Hexafluoride 0 .263g (Pandey et al. 56)The explanation behind this is that heavier gas samples have larger weight than the lighter ones. The gas sample cannot have more weight in this experiment as a result of change in the volume of the samples. Therefore, the change must be linked to the chain reactor of the particles of the gas. On plott ing the molecular weights against the experimental weights, the experimentalist found out that it was a straight line. This is as a result of the coefficient of correlation between the mass of the constant samples and the molecular mass. Therefore, this leads to the accepting the hypothesis that it is possible to determine the molecular mass of a sample of gas simply by measuring the constant quantity against an already inflexible linear relationship Pandey et al.
