WebMar 25, 2024 · The formula mass of a compound is the mass of the elements with their number of atoms as in the empirical formula. given the empirical formula is CH₂. atomic mass of C = 12 g/mol. atomic mass of H = 1 g/mol. then formula mass = 12 + 2 = 14 g. Divide the molar mass by formula mass; molar mass = 70.13 g. 70.13 g/14 g = 5 Web9. Find the Molecular Formula of a substance with the following condition: EMPIRICAL FORMULA: CH4 MOLAR MASS OF COMPOUND: 64.2 g/mol Answer:C₄H₁₆. This is the molecular formula. 10. what is the molar mass of methane (CH4) if there are 0.623 moles in a 10.0g sample Explanation:

Multiply each of the moles by the smallest whole number that will convert each into a whole number. Fe:O = 2 (1:1.5) = 2:3. Since the moles of O is still not a whole number, both moles can be multiplied by 2, while rounding to a whole number. how to revert last commit
