Because an individual molecule of sugar weighs more than an individual molecule of water. Avogadro's number equals the number of (A) atoms in one mole of O2 (B) atoms in one mole of atoms. How many hydrogen atoms? The factor-label method yields the desired cancellation of units, and the computed result is on the order of 1022 as expected. 3. The mass in grams of 1 mole of substance is its molar mass. The given mass of K (4.7 g) is a bit more than one-tenth the molar mass (39.10 g), so a reasonable ballpark estimate of the number of moles would be slightly greater than 0.1 mol. This relationship holds for all elements, since their atomic masses are measured relative to that of the amu-reference substance, 12C. One of these amino acids is glycine, which has the molecular formula C2H5O2N. This is because marshmallows are not very dense.

In that case, it is clear that lead has the larger number of moles. If we're converting from grams of sulfuric acid to moles of sulfuric acid, we need to multiply by the reciprocal of the molar mass to do so, or 1 mole/98.08 grams. E) moles in 6.02 10 amu of an element. On the other hand, if you need something that is heavy and will sink to the bottom of a container, then lead is what you need. 2003-2023 Chegg Inc. All rights reserved. We can derive the number of moles of a compound from its mass following the same procedure we used for an element in Example 3: The molar mass of glycine is required for this calculation, and it is computed in the same fashion as its molecular mass. Lead atoms are much larger than sugar atoms. To do this, we simply need to multiply the mass of one marshmallow by the Avogadro's number.

This means that lead is approximately 180 times more dense than marshmallows. 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. Marshmallows, on the other hand, are fluffy, light, and airy. 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). The masses of 1 mole of different elements, however, are different, since the masses of the individual atoms are drastically different.
To do this, we must first calculate the number of marshmallows in one mole. The molar amount of a substance may be calculated by dividing its mass (g) by its molar mass (g/mol): The factor-label method supports this mathematical approach since the unit g cancels and the answer has units of mol:, [latex]4.7\cancel{\text{g}}\text{K}\left(\frac{\text{mol K}}{39.10\cancel{\text{g}}}\right)=0.12\text{mol K}[/latex]. Example shows 12 doughnuts as one dozen, 500 sheets of paper as 1 ream, and 6.022 times 10 to the power of 23 molecules as 1 mole. Avogadro's number is the number of.
