WebThe overall chemical equation says that 1 mole of glucose reacts with 6 moles of oxygen gas for the reaction to occur. So the glucose to oxygen ratio is 1:6, or basically we need 6 times as many moles of oxygen gas as we do glucose for the reaction to happen. So 0.129 x 6 = 0.833 moles of oxygen. Hope that helps.
WebJul 21, 2024 · The "non-whole number" empirical formula of the compound is Fe 1 O 1.5. 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. the batman who laughs seriesWebJul 21, 2024 · The units for molar mass are grams per mole or g/mol. 1.00mol of carbon-12 atoms has a mass of 12.0g and contains 6.022 × 1023 atoms. 1.00 mole of any element has a mass numerically equal to its atomic mass in grams and contains 6.022 × 1023 … Unlike molecules, which form covalent bonds, ionic compounds do not have a … the batman who laughs tattooWeb74 Likes, 5 Comments - Sarah Aguilar Flaschka (@elnidoyelsentido) on Instagram: "He escuchado muchas veces que la cocina es ingrata.
