Globalizethis aggregates which sample has the largest mass 1 mole of marshmallows information to help you offer the best information support options. Mathematically, this is written as. For given moles of sample, find (a) mass of the sample, (b) molecules in the sample, and (c) atoms in the sample. which sample has the largest mass 1 mole of marshmallows Which sample has the greatest mass? (multiple choice) A mole is defined as the amount of substance containing the same number of discrete entities (atoms, molecules, ions, etc.) There are many factors to consider when determining which substance is more dense, marshmallows or lead. Experimental measurements have determined the number of entities composing 1 mole of substance to be [latex]6.022\times {10}^{23}[/latex], a quantity called Avogadros number. To figure this out, you will need the molar mass of NaCl which is 58.44 g/mol. Diamond is one form of elemental carbon. The given mass of K (4.7 g) is a bit more than one-tenth the molar mass (39.10 g), so a reasonable ballpark estimate of the number of moles would be slightly greater than 0.1 mol. Therefore the result will be 78,0452 g. To calculate the mass of O2, we first need to divide the result by the Avogadro constant. What is the empirical formula for the compound? This result is consistent with our rough estimate. The mass of K is provided, and the corresponding amount of K in moles is requested. PQ-1. Because an individual molecule of sugar weighs more than an individual molecule of water. This means that the sample with the largest mass of 1 mole of marshmallows would be the one with the greatest number of marshmallows. This means that, for the same volume, lead is about 56 times heavier than marshmallows.
