P = nRT P= 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 1, 2024 · The Ideal Gas Law is a single equation which relates the pressure, volume, temperature, and number of moles of an ideal gas. If we substitute in the variable R for the constant, the equation becomes: P × V T × n = R. The Ideal Gas Law is conveniently rearranged to look this way, with the multiplication signs omitted:
WebAvogadro’s law states that the number of moles of a gas and the volume of the gas are directly proportional. Avogadro’s law can be represented by the equation 𝑉 = 𝑛 𝑉, where 𝑉 is the volume of the gas, 𝑛 is the number of moles, and 𝑉 is the molar volume.
