Achemist finds that 30.82 g of nitrogen will react with 17.60 g, 35.20 g, 70.40 g, or 88.00 g of oxygen to form four different compounds.

Achemist finds that 30.82 g of nitrogen will react with 17.60 g, 35.20 g, 70.40 g, or 88.00 g of oxygen to form four different compounds. calculate the mass of oxygen per gram of nitrogen in each compound.

Answer : The mass of oxygen per gram of nitrogen for four different oxygen are, 0.57, 1.14, 2.28 and 2.85 grams respectively. Explanation : First we have to calculate the mass of oxygen per gram of nitrogen for oxygen 1. As, 30.82 g of nitrogen will react with 17.60 g of oxygen So, 1 g of nitrogen will react with of oxygen Now we have to calculate the mass of oxygen per gram of nitrogen for oxygen 2. As, 30.82 g of nitrogen will react with 35.20 g of oxygen So, 1 g of nitrogen will react with of oxygen First we have to calculate the mass of oxygen per gram of nitrogen for oxygen 3. As, 30.82 g of nitrogen will react with 70.40 g of oxygen So, 1 g of nitrogen will react with of oxygen First we have to calculate the mass of oxygen per gram of nitrogen for oxygen 4. As, 30.82 g of nitrogen will react with 88.00 g of oxygen So, 1 g of nitrogen will react with of oxygen Therefore, the mass of oxygen per gram of nitrogen for four different oxygen are, 0.57, 1.14, 2.28 and 2.85 grams respectively.

Let us calculate the mass of oxygen per gram of nitrogen in each compound. First compound Second compound Third compound Fourth compound How do the numbers above support Dalton’s atomic theory? Let’s find out the ratio that connects the results between the first, second, and third compounds above. Between the first and second compounds: Between the second and third compounds: Between the first and third compounds: It all obeys the law of multiple proportions because the ratio is simple whole numbers. Notes: The law of multiple proportions was put forward by John Dalton. This law is one of the basic laws of stoichiometry.The law of multiple proportions states: if two elements can form more than one compound, the ratio of the mass of one element, which is compounded with a certain number of other elements, can be expressed in small whole-number ratios.Learn moreThe chemical formula of a compound

The mass of oxygen per gram of nitrogen is 0.57 Explanation:  Given Mass of Nitrogen (N2) = 30.82 g Given Mass of Oxygen (O2) = 17.60 g Thus the mass of oxygen per gram of nitrogen can be calculated by dividing the given mass of the oxygen by the given mass of the nitrogen. Thus, Mass of oxygen per gram of nitrogen = 17.60 g / 30.82 g = 0.57 Thus the answer is 0.57

17.60 g / 30.82 = 0.57   35.20g / 30.82 = 1.14 (twice as much oxygen as the first)   70.40 / 30.82 = 2.28 (4 X’s as much oxygen as the first)   88.00 / 30.82 = 2.85 (5 X’s as much oxygen as the first)   “the law of multiple proportions to the idea that chemical combination consists in the interaction of atoms of definite and characteristic weight”

The mass of oxygen per gram of nitrogen in compound = 0.571 Further explanation Dalton’s law of multiple comparisons states that if elements are forming two or more kinds of compounds, if the mass of one of the elements is known to be the same / fixed, then the mass of the second element in the two compounds will have a ratio as a simple integer.
