Question

Quizplus · Accepted Answer

The formula N₂ decodes to N2S (Nitrogen disulfide). The molar mass of N2S is calculated as follows: Nitrogen (N) has an atomic mass of approximately 14 g/mol, and there are two nitrogen atoms, so 2 * 14 = 28 g/mol. Sulfur (S) has an atomic mass of approximately 32 g/mol, and there is one sulfur atom, so 1 * 32 = 32 g/mol. Adding these together gives a molar mass of 60 g/mol for N2S. At STP (standard temperature and pressure), 1 mole of any gas occupies 22.4 liters. Therefore, the density of N2S at STP can be calculated as the mass of 1 mole divided by the volume of 1 mole at STP: 60 g / 22.4 L = 2.68 g/L. However, since this option is not available and there seems to be a misunderstanding in the calculation or the interpretation of the formula, the correct approach to find the density of a gas at STP would typically involve using the molar mass and the volume occupied by 1 mole of gas at STP. Given the options and the potential for a typo or misinterpretation in the question or answer choices, the closest correct choice provided in the options based on standard calculations is not directly listed, indicating a need for clarification.
