The number of Cu atoms in the wire may be conveniently derived from its mass by a two-step computation: first calculating the molar amount of Cu, and then using Avogadros number (NA) to convert this molar amount to number of Cu atoms: Considering that the provided sample mass (5.00 g) is a little less than one-tenth the mass of 1 mole of Cu (~64 g), a reasonable estimate for the number of atoms in the sample would be on the order of one-tenth NA, or approximately 1022 Cu atoms.

The answer is clear: lead is much more dense than marshmallows.
By the end of this section, you will be able to: The identity of a substance is defined not only by the types of atoms or ions it contains, but by the quantity of each type of atom or ion. Although this represents just a tiny fraction of 1 mole of water (~18 g), it contains more water molecules than can be clearly imagined. two old goats arthritis formula reviews . This means that, for the same volume, lead is much denser than marshmallows. moi-1 What is the most likely formula for the stable ion of X?

Which of the following statements is FALSE? In other words, a single marshmallow has close to 30% more volume than an entire chunk of lead! Therefore, 20.0 g H2O represents the least number of molecules since it has the least number of moles. How big is a mole? How many copper atoms are in 5.00 g of copper wire?

PQ-1. Which sample has the largest mass? (A) 1 mole of marshmallows A large marshmallow might weigh the same as a small piece of lead, but it will take up a lot more space. As for elements, the mass of a compound can be derived from its molar amount as shown: The molar mass for this compound is computed to be 176.124 g/mol. Which of the following statements is FALSE? All spontaneous reactions occur quickly. All of the above are true. This means that there are lead atoms. 12(12.011) + 22(1.00794) + 11(15.9994) = 342.300 g/mol; Then [latex]0.0278\text{mol}\times 342.300\text{g/mol}=9.52\text{g sugar. This relationship holds for all elements, since their atomic masses are measured relative to that of the amu-reference substance, 12C. First, marshmallows are made mostly of sugar, while lead is a heavy metal. Therefore, even though marshmallows have a greater volume, lead is significantly heavier. The given number of moles is a very small fraction of a mole (~10-4 or one-ten thousandth); therefore, we would expect the corresponding mass to be about one-ten thousandth of the molar mass (~0.02 g). Your email address will not be published. Compare 1 mole of H2, 1 mole of O2, and 1 mole of F2. This means that the sample with the largest mass of 1 mole of marshmallows would be the one with the greatest number of marshmallows.
