The correct answer is 6.02 10 23 molecules of O 2.. Key Points. Which of the following has the largest number of molecules? 7.1 The Mole Concept | Introductory Chemistry - Lumen Learning which sample has the largest mass 1 mole of marshmallows The density of a substance is the mass of the substance divided by the volume of the substance. PQ-1. From the moles, calculate the number of atoms and the mass of the elements involved. Answer: This can also be written as 6.02210 23 mol-1. There are many factors to consider when determining which substance is more dense, marshmallows or lead. A. The mole provides a method for how to count atoms in a sample. The masses of 1 mole of different elements, however, are different, since the masses of the individual atoms are drastically different. Because an individual molecule of sugar weighs more than an individual molecule of water. Marshmallows are made of sugar, air, corn syrup, and gelatin. Since the amount of Ar is less than 1 mole, the mass will be less than the mass of 1 mole of Ar, approximately 40 g. The molar amount in question is approximately one-one thousandth (~103) of a mole, and so the corresponding mass should be roughly one-one thousandth of the molar mass (~0.04 g): In this case, logic dictates (and the factor-label method supports) multiplying the provided amount (mol) by the molar mass (g/mol): [latex]9.2\times {10}^{-4}\cancel{\text{mol}}\text{Ar}\left(\frac{39.95\text{g}}{\cancel{\text{mol}}\text{Ar}}\right)=0.037\text{g Ar}[/latex]. The density of marshmallows is 0.5 grams per cubic centimeter. Beryllium is a light metal used to fabricate transparent X-ray windows for medical imaging instruments. While atomic mass and molar mass are numerically equivalent, keep in mind that they are vastly different in terms of scale, as represented by the vast difference in the magnitudes of their respective units (amu versus g). Which sample has the largest mass? Which sample has the largest mass? So, how many molecules do we need in order to have "a whole lot"? You can refer to the answers, The following summaries about unscented goat milk soap will help you make more personal choices about more accurate and faster information. Find the number of carbon atoms by multiplying Avogadros number by the number of moles: [latex]\frac{3104\cancel{\text{carats}}\times \frac{200\cancel{\text{mg}}}{1\cancel{\text{carat}}}\times \frac{1\cancel{\text{g}}}{1000\cancel{\text{mg}}}}{12.011\cancel{\text{g}}\cancel{{\text{mol}}^{-1}}\left(6.022\times {10}^{23}\cancel{{\text{mol}}^{-1}}\right)}=3.113\times {10}^{25}\text{C atoms}[/latex], 23. Today, we possess sophisticated instruments that allow the direct measurement of these defining microscopic traits; however, the same traits were originally derived from the measurement of macroscopic properties (the masses and volumes of bulk quantities of matter) using relatively simple tools (balances and volumetric glassware). Which sample has the largest mass? Which sample has the largest mass? Which sample has the largest mass? How many C4H10 molecules are contained in 9.213 g of this compound? luminosity.
