Thus 0.25 mol of methane requires 2 x 0.25 = 0.50 mol of oxygen. One mole of any gas occupies 22.4 dm 3 by volume at STP. Volume of oxygen required = 22.4 x No. of moles = 22.4 x 0.5 = 11.2 dm 3 Example – 05:

2.5: The Law of Multiple Proportions and Dalton’s Atomic Theory

WebThe Law of Multiple Proportions states that the masses of one element which combine with a fixed mass of the second element are in a ratio of whole numbers. Hence, the masses of oxygen in the two compounds that combine with a fixed mass of carbon should be in a whole-number ratio. WebThis law can be considered as another form of the law of definite proportions. The only difference between these two laws of chemical combination is that Gay Lussac’s Law is stated with respect to volume while the law of definite proportions is stated with respect to mass. 5.
