Shows how many molecules are present
Web2 moles ⋅ 22.4 L/mol = 44.8 L. For 0.5 moles the volume will be. 0.5 moles ⋅ 22.4 L/mol = 11.2 L, and so on. The molar volume of a gas is derived from the ideal gas law P V = nRT: P V = nRT → V = nRT P → V n = RT P. Let's say you were given a temperature of 355 K and a pressure of 2.5 atm, and asked to determine the gas' molar volume at ... WebExpert Answer 100% (1 rating) 7.

WebMolecular and Empirical Formulas. A molecular formula is a representation of a molecule that uses chemical symbols to indicate the types of atoms followed by subscripts to show the number of atoms of each type in the molecule. (A subscript is used only when more than one atom of a given type is present.) Molecular formulas are also used as abbreviations … WebSo to determine how many moles of oxygen atoms are present in a sample of glucose, we simply need to multiple the moles of glucose by six. So if we have 0.139 mols of glucose, we will have 0.833 mols of oxygen (0.139 x 6 = 0.834, but accounting for sig figs it becomes 0.833). Hope that helps. Comment ( 8 votes) Upvote Downvote Flag more
