A large marshmallow might weigh the same as a small piece of lead, but it will take up a lot more space. Lead atoms are held together by metallic bonds, which are very strong. Save my name, email, and website in this browser for the next time I comment. This means that the sample with the largest mass of 1 mole of marshmallows would be the one with the greatest number of marshmallows. When it comes to lead, it is important to note that its weight makes up for what it lacks in volume. D) All of these have the same mass. (A) 10 grams of CH4 (B) 10 grams of HC1 (C) 10 grams of H2 (D) 10 grams of PH3. Required fields are marked *. Figure 1. How many atoms are present in the diamond? Due to the use of the same reference substance in defining the atomic mass unit and the mole, the formula mass (amu) and molar mass (g/mol) for any substance are numerically equivalent (for example, one H2O molecule weighs approximately18 amu and 1 mole of H2O molecules weighs approximately 18 g). Although this represents just a tiny fraction of 1 mole of water (~18 g), it contains more water molecules than can be clearly imagined. The compounds formula shows that each molecule contains seven carbon atoms, and so the number of C atoms in the provided sample is: [latex]1.31\times {10}^{20}{\text{C}}_{7}{\text{H}}_{5}{\text{NO}}_{3}\text{S molecules}\left(\frac{7\text{C atoms}}{1{\text{C}}_{7}{\text{H}}_{5}{\text{NO}}_{3}\text{S molecule}}\right)=9.20\times {10}^{21}\text{C atoms}[/latex].

Clock-wise from the upper left: 130.2g of C8H17OH (1-octanol, formula mass 130.2 amu), 454.9g of HgI2 (mercury(II) iodide, formula mass 459.9 amu), 32.0g of CH3OH (methanol, formula mass 32.0 amu) and 256.5g of S8 (sulfur, formula mass 256.6 amu). A sine wave with wavelength \lambda and period T is described by A \sin ( 2 \pi ( x / \lambda - t / T ) ) Asin(2(x/t/T )) is superposed on another with wavelength 2 \lambda 2 and period 2T. This means that lead is approximately 180 times more dense than marshmallows. Compare 1 mole of H2, 1 mole of O2, and 1 mole of F2. Now, you can go from moles of sucrose to number of molecules of sucrose by using Avogadro's constant, which is essentially the definition of a mole. So one molecule of water will have a smaller mass than one molecule of sugar, since it contains fewer atoms. 10 grams of H2.

Is the gravitational force between 1 kg of lead and Earth the, which one of the samples has the largest mass?A.1 mole of CO2 . l type='a'> 0.341 mole of potassium nitride 2.62 mmol of neon (1 mmol = 1/1000 mol) 0.00449 mole of manganese (II) oxide 7.18105moles of silicon dioxide 0.00021 mole of iron (III) phosphate. The calculated magnitude (0.12 mol K) is consistent with our ballpark expectation, since it is a bit greater than 0.1 mol. Which has the greatest mass? Which sample has the largest mass? Let's assume that we are talking about a standard sized marshmallow and a lead atom. A. Avogadro's number, #6.022 * 10^(23)#. To put that into perspective, a single marshmallow only weighs about 2 grams. Analysis of a sample of a covalent compound showed that it contained 14.4% hydrogen and 85.6% carbon by mass. One mole is 6.022 x 10 23 of the microscopic particles which make up the substance in question.
