Yes, Marshmallow Fluff weighs the same as regular marshmallows. Which of the following represents the least number of molecules? 21. From left to right (bottom row): 32.1g sulfur, 28.1g silicon, 207g lead, and 118.7g tin. XeFn, where n is a whole number. However, lead is generally much denser than marshmallows, meaning that it has a higher mass per unit of volume. An intraoperative cholangiogram shows that the ducts are finally cleared of stones at the conclusion of the surgery. (A) 10 grams of CH4 (B) 10 grams of HC1 (C) 10 grams of H2 (D) 10 grams of PH3. which sample has the largest mass 1 mole of marshmallows. Marshmallows are made mostly of sugar and air, while lead is a very dense metal. Answer: This can be done by using the density of marshmallows. Calculate the number of moles of each species, then remember that 1 mole of anything [latex]=6.022\times {10}^{23}[/latex] species. which sample has the largest mass 1 mole of marshmallows Sample Questions - Chapter 2 - Texas A&M University Correct option is A) 4 g of hydrogen contains the largest number of atoms. How many copper atoms are in 5.00 g of copper wire? lead is a very heavy metal, so even a small piece of lead can weigh a lot. 1 mol H atoms = 6.02 X 10 H atoms.

How to Calculate the Number of Molecules | Sciencing Which sample has the largest mass? - 29903591. brockmorrison2003 brockmorrison2003 12/13/2022 Chemistry High School answered expert verified Which sample has the largest mass? A mole is a unit of measurement that is used to measure the amount of a substance. This constant is properly reported with an explicit unit of per mole, a conveniently rounded version being [latex]6.022\times {10}^{23}\text{/mol}[/latex]. physical science. The number of entities composing a mole has been experimentally determined to be [latex]6.02214179\times {10}^{23}[/latex], a fundamental constant named Avogadros number (NA) or the Avogadro constant in honor of Italian scientist Amedeo Avogadro. The mass of one atom of carbon-12 the atomic mass of carbon-12 is exactly 12 atomic mass units. This experimental approach required the introduction of a new unit for amount of substances, the mole, which remains indispensable in modern chemical science. Copper reacts with dilute nitric acid according to the following equation: 3Cu(s)+8HNO3(aq)3Cu(NO3)2(aq)+2NO(g)+4H2O(l)3 \mathrm{Cu}(s)+8 \mathrm{HNO}_3(a q) \underset{3 \mathrm{Cu}\left(\mathrm{NO}_3\right)_2(a q)+2 \mathrm{NO}(g)+4 \mathrm{H}_2 \mathrm{O}(l)}{\longrightarrow} Its formula has twice as many oxygen atoms as the other two compounds (one each). . In order to answer this question, we must first understand what a mole is. This means that there are lead atoms. (A) I mole of marshmallows (C) 1 mole of C02 (carbon dioxide) molecules (B) I mole of Pb (lead) atoms (D) All of these have the same mass.
