To calculate the percent composition of dinitrogen tetroxide (N₂O₄), first determine its molar mass by adding the atomic masses of its constituent elements: nitrogen (N) and oxygen (O). Dinitrogen tetroxide has 2 nitrogen atoms (2 × 14.01 g/mol) and 4 oxygen atoms (4 × 16.00 g/mol), giving a total molar mass of approximately 92.02 g/mol. Next, calculate the percent composition of each element by dividing the total mass of each element in the formula by the overall molar mass and multiplying by 100. For nitrogen, it would be (28.02 g/mol / 92.02 g/mol) × 100, and for oxygen, (64.00 g/mol / 92.02 g/mol) × 100.

How does one determine a percent composition from an empiricle formula?
To determine the percent composition from an empirical formula, first calculate the molar mass of the compound by summing the atomic masses of all the elements in the formula. Next, for each element, divide its total mass in the empirical formula by the molar mass of the compound and multiply by 100 to get the percent composition. This process gives the percentage of each element in the compound relative to the total mass.
What is the percent composition of (NH4)2S?
To find the percent composition of (NH₄)₂S, first calculate the molar mass. The molar mass of (NH₄)₂S is approximately 68.17 g/mol (14.01 g/mol for N, 1.01 g/mol for H, and 32.07 g/mol for S). The percent composition can be calculated as follows: Nitrogen (28.02 g) contributes about 41.2%, Hydrogen (8.08 g) contributes about 11.9%, and Sulfur (32.07 g) contributes about 47.0%. Thus, the percent composition is approximately 41.2% N, 11.9% H, and 47.0% S.
What is the percent composition of CI in MgCI2?
To find the percent composition of chlorine (Cl) in magnesium chloride (MgCl₂), first calculate the molar mass of MgCl₂. The molar mass of magnesium (Mg) is approximately 24.31 g/mol, and that of chlorine (Cl) is about 35.45 g/mol. Thus, the molar mass of MgCl₂ is 24.31 + (2 × 35.45) = 95.21 g/mol. The percent composition of Cl is then calculated as (2 × 35.45 / 95.21) × 100%, which is approximately 74.4%.
