So, in order to answer the question, "Which sample has the largest mass 1 mole of marshmallows? Which sample has the largest mass? How many hydrogen atoms? Therefore, 20.0 g H2O represents the least number of molecules since it has the least number of moles. which sample has the largest mass 1 mole of marshmallows. There are a few key differences between marshmallows and lead. Lead's atomic number is 82, which means that it has 82 protons in its nucleus. This means that, all else being equal, lead would have the larger mass. How many moles of glycine molecules are contained in 28.35 g of glycine? So, which is more dense, marshmallows or lead? Explain why. A mole is a unit of measurement that is used to measure the amount of a substance. Moleis a counting unit in chemistry used 3.01 10 molecules. Marshmallows, on the other hand, are very light and fluffy. This is because lead is a metal and marshmallows are made mostly of sugar and air. This means that, for the same volume, lead is much denser than marshmallows. This would be the sample with the mass of 3.011 x 10^23 grams. mrs elliott WordPress.com, 5.Chem 104 ACS Final CHAPTER 3 Flashcards Quizlet, 7.What is the Mole Concept? 7. The SI unit of Avogadro's number is inverse . The number of molecules in a single droplet of water is roughly 100 billion times greater than the number of people on earth. 3. The mole provides a link between an easily measured macroscopic property, bulk mass, and an extremely important fundamental property, number of atoms, molecules, and so forth. 5.The two masses have the same numerical value, but the units are different: The molecular mass is the mass of 1 molecule while the molar mass is the mass of [latex]6.022\times {10}^{23}[/latex] molecules.
