For example, 12 marshmallows =1 dozen marshmallows. The density of marshmallows is 0.5 grams per cubic centimeter. The masses of 1 mole of different elements, however, are different, since the masses of the individual atoms are drastically different. Lead is much heavier than marshmallows. Consistent with its definition as an amount unit, 1 mole of any element contains the same number of atoms as 1 mole of any other element. lead is a very dense metal, so it is very heavy. 1 mole of pennies would cover the Earth 1/4 mile deep! The most important factor is the composition of each substance. Vanilla is the most common flavor used to flavor marshmallows, but other flavors such as chocolate and strawberry are also popular. Because an individual molecule of sugar weighs more than an individual molecule of water. 3.01 10 molecules. 100/1000 x 0.1 = 0.01 moles.

However, because a hydrogen peroxide molecule contains two oxygen atoms, as opposed to the water molecule, which has only one, the two substances exhibit very different properties. From left to right (top row): 65.4g zinc, 12.0g carbon, 24.3g magnesium, and 63.5g copper. Which sample has the largest mass? The mole is used in chemistry to represent [latex]6.022\times {10}^{23}[/latex] of something, but it can be difficult to conceptualize such a large number. (a) 1 mol of CO 2 (g) (b) 1 mol of UF 6 (g) (c) 1 mol of CH 3 COCH 3 (l) (d) 1 mol of He(g) . How do you calculate the number of moles from volume? The mass of one atom of carbon-12 the atomic mass of carbon-12 is exactly 12 atomic mass units. to determine its molecular formula, it is necessary to know: answer choices. So, which is more dense, marshmallows or lead? When it comes to lead, it is important to note that its weight makes up for what it lacks in volume. To do this, we simply need to multiply the mass of one marshmallow by the Avogadro's number. Which sample has the largest mass? Start your trial now! nceptual (A) 1 mole of marshmallows (B) 1 mole of Pb (lead) atoms (C) 1 mole of CO2 (carbon dioxide) molecules (D) All of these have the same mass. 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). In order to answer this question, we must first understand what a mole is. A liter of air contains [latex]9.2\times {10}^{-4}[/latex] mol argon. To calculate the mass of 1 mol of Na2S we need just to multiply it by it's molar mass: 78,0452 g/mol. How many carbon atoms were present in the stone. However, lead is generally much denser than marshmallows, meaning that it has a higher mass per unit of volume. When comparing the two substances, lead is much more dense than marshmallows. This gives us a mass of 1 mole of marshmallows as 3.011 x 10^23 grams. Which sample has the largest mass? bags of regular marshmallows in a carton. 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. Performing the calculation, we get: [latex]1.42\times {10}^{-4}\cancel{\text{mol}}\text{vitamin C}\left(\frac{176.124\text{g}}{\cancel{\text{mol}}\text{vitamin C}}\right)=0.0250\text{g vitamin C}[/latex]. (D) atoms in one mole of atoms and marbles in one mole of marbles, (D) atoms in one mole of atoms and marbles in one mole of marbles, Which sample contains the least number of atoms? Now that we know the number of marshmallows in one mole, we can calculate the mass of one mole of marshmallows. How big is a mole? Determine the number of grams present in the diamond and from that the number of moles. Lead atoms are much larger than sugar atoms. (b) Which has the greatest mass? This is because marshmallows are made up of mostly sugar, which has a high molar mass, while lead is a metal with a relatively low molar mass. 1. Answers One : Question Lists Recent : PLEASE WALK ME THROUGH THIS: The bus to the exposition averaged 18 miles to a gallon of gas . 10+ which sample has the largest mass 1 mole of marshmallows most standard, 1.Solved 61. This is what a mole actually means, a very, very large collection of molecules. The result is in agreement with our expectations as noted above, around 0.04 g Ar. Marshmallows have a larger atomic mass than lead. This is because marshmallows are not very dense. Which sample has the largest mass? Experts are tested by Chegg as specialists in their subject area. The calculated magnitude (0.12 mol K) is consistent with our ballpark expectation, since it is a bit greater than 0.1 mol.
