According to the Periodic Table, silver (Ag) has an Atomic Mass of about 108 grams per mole. If you have 802 grams, set up a direct proportion where 108/1=802/x and solve for x. You get about 7.43 moles of silver.
What else can I help you with?
If a sample of pure silver (Ag) contains 3.35 x 1022 atoms of silver how many moles of silver are in the sample?
To find the number of moles of silver, you can use Avogadro's number, which is approximately (6.022 \times 10^{23}) atoms/mole. The number of moles can be calculated using the formula: [ \text{moles} = \frac{\text{number of atoms}}{\text{Avogadro's number}} = \frac{3.35 \times 10^{22}}{6.022 \times 10^{23}} \approx 0.0556 \text{ moles}. ] Thus, the sample contains approximately 0.0556 moles of silver.
Is the number of atoms in a sample directly related to the mass of that sample?
If the chemical composition of the sample is known, then the answer is yes. However, equal masses of platinum and magnesium, for example, contain quite different numbers of atoms, because the atomic mass of platinum is much higher than that of magnesium.

How many atoms are in a 0.84 lb sample of silver?
To find the number of atoms in a sample of silver, we first need to convert the mass from pounds to grams. Then we calculate the number of moles of silver using the molar mass of silver. Finally, we use Avogadro's number to convert moles to atoms. The answer would be approximately 2.0 x 10^23 atoms in a 0.84 lb sample of silver.
A sensitive balance can detect masses of 1 10-8 g How many atoms of silver would be in a sample having this mass?
To find the number of atoms in the sample, you would first calculate the number of moles of silver in 1 x 10^-8 g using the molar mass of silver (107.87 g/mol). Then, you would use Avogadro's number (6.022 x 10^23 atoms/mol) to convert moles to atoms.

Which sample contains the greatest number of atoms a sample of Mn that contains 3.29E plus 24 atoms or a 5.18 mole sample of you?
Which sample contains the greatest number of atoms. A sample of Mn that contains 3.29E+24 atoms or a 5.18 mole sample of I?The sample of _____ contains the greatest number of atoms.Answer:In order to compare the two samples, it is necessary to express both quantities in the same units. Since the question was phrased in terms of atoms, it is convenient to convert moles of I to atoms of I.The conversion factor between atoms and moles is Avogadro's number: 6.02 x 1023 "things" / molTo convert 5.18 moles of I to atoms of I:atoms I= 5.18 mol I6.02 x 1023 atoms I = 3.12E+24 atoms I1 mol IMultiply by atoms per mole. Moles cancel out.The sample of Mn contains 3.29E+24 atoms.Since 3.12E+24 is smaller than 3.29E+24, the sample of Mn contains the greatest number of atoms.
