Best Answer 100% (1 rating) A substance with the empirical formula C2HCL (the 2 is a subscript) has the molar mass of 181.44 g/mol. C4H9, 114.17g/mol CCl, 189.82g/mol C3H2N, 156.18g/mol C6H7N, 279.40g/mol C2HCl, 120.98g/mol C5H10NS2, 593.11g/mol Find the molecular formula of each compound. Express your answer as a chemical formula. Calculations: Formula: c2hCl Molar Mass: 60.4829 g/mol 1g=1.65335987527053E-02 mol Percent composition (by mass): Element Count Atom Mass %(by mass) Find the molecular formula of this compound. The empirical formula and molar mass of several compounds are listed below. Determine the empirical formula of the compound. C2HCl, 120.96g/mol. Find the molecular formula of each compound. Mass of empirical formula = (2 x 12.01) + 1.008 + 35.45 = 60.478 g/mol. C6H7N, 186.24 g/mol C2HCl, 181.44 g/mol C5H10NS2,296.54 g/mol - 13125553 Fórmula no sistema Hill é C2HCl: Calculando a massa molar (peso molar) To calculate molar mass of a chemical compound enter its formula and click 'Compute'. Part B. C2HCl, 181.46 g/mol. Find the molecular formula of each compound. 1) A compound has the following percentages by mass: barium, 58.84%; sulfur, 13.74%; oxygen, 27.43%. a. C6H7N, 186.24 g>mol b. C2HCl, 181.44 g>moâ¦ Express your answer as a chemical formula. mol â1 Appearance Colorless gas Odor: Pungent, ethereal: Density: 0.921 g/cm 3 (0-4 °C) 0.8898 g/cm 3 (25 °C) Melting point â138.7 °C (â217.7 °F; 134.5 K) Boiling point: 12.27 °C (54.09 °F; 285.42 K) decomposes at 510 °C To do this divide the molar mass by the mass of the empirical formula. Na fórmula química, você pode usar: Qualquer elemento químico. molar mass / empirical mass = 179 g/mol / 60.478 g/mol = 2.960 ~ 3 From the given empirical formula and molar mass, find the molecular formula of each compound. What is the molecular formula? Express your answer as a chemical formula. To work out the molecular formula figure out how many times the empirical formula fits into the molar mass. Ex: The molar mass of a compound is 181.50 g/mol and the empirical formula is C2HCl. The empirical formula and molar mass of several compounds are listed. Ex: Find the empirical formula for a compound containing only carbon and hydrogen if it is known to contain 84.21% carbon. Chemistry. Part A. C6H7N, 279.41 g/mol. Part C. C5H10NS2, 593.13 g/mol. C5H10NS2, 444.85g/mol The molar mass and empirical formula of several compounds are listed below.
