To calculate the mass of 1.2044 × 10²⁴ atoms of lead (Pb), first determine the number of moles using Avogadro's number (approximately 6.022 × 10²³ atoms/mol). The number of moles is calculated as ( \frac{1.2044 \times 10^{24}}{6.022 \times 10^{23}} \approx 2.00 ) moles. The molar mass of lead is about 207.2 g/mol, so the mass is ( 2.00 , \text{moles} \times 207.2 , \text{g/mol} \approx 414.4 , \text{grams} ).
To calculate the number of atoms in 3.4 grams of hydrogen peroxide, you first convert the grams to moles using the molar mass of hydrogen peroxide. Then, you use Avogadro's number to convert moles to atoms. There are approximately 6.022 x 10^23 atoms in 1 mole of a substance.

35.2 grams C6H8O (1 mole C6H8O/96.124 grams)(6.022 X 1023/1 mole C6H8O)= 2.21 X 1023 atoms of vitamin C===========================
To calculate the number of atoms in 10 grams of gold, first determine the molar mass of gold, which is approximately 197 grams per mole. Using Avogadro's number, which is (6.022 \times 10^{23}) atoms per mole, you can find the number of moles in 10 grams of gold by dividing 10 grams by the molar mass (197 g/mol). Finally, multiply the number of moles by Avogadro's number to find the total number of atoms: [ \text{Number of atoms} = \left( \frac{10 \text{ g}}{197 \text{ g/mol}} \right) \times 6.022 \times 10^{23} \text{ atoms/mol} \approx 3.05 \times 10^{22} \text{ atoms}. ]

To calculate the grams of phosphorus, you need to know the molar mass of phosphorus and then use Avogadro's number to convert from atoms to grams. The molar mass of phosphorus is approximately 30.97 g/mol. Therefore, you can calculate the grams of phosphorus using this information.
To calculate the number of carbon atoms in 2.50 grams of theobromine (C7H8N4O2), you first need to find the molar mass of theobromine. The molar mass of theobromine is 180.16 g/mol. From the molecular formula, there are 7 carbon atoms in one molecule of theobromine. Therefore, using the molar mass and the number of carbon atoms in the molecule, you can calculate the number of carbon atoms in 2.50 grams.
To calculate the number of atoms in 3.4 grams of hydrogen peroxide, you first convert the grams to moles using the molar mass of hydrogen peroxide. Then, you use Avogadro's number to convert moles to atoms. There are approximately 6.022 x 10^23 atoms in 1 mole of a substance.

To determine the number of atoms in 5.72 grams of glucose, you first need to calculate the number of moles of glucose using its molar mass. Then, you can use Avogadro's number (6.022 x 10^23 atoms/mol) to convert moles to atoms. Given that the molar mass of glucose is approximately 180.16 g/mol, you can then calculate the number of atoms in 5.72 grams of glucose.
To calculate the weight of a mole of an atom in grams (molar mass), you add up the atomic masses of all the atoms in one mole of the substance. This can be found on the periodic table and is usually given in atomic mass units (amu). The molar mass is expressed in grams per mole.
To calculate the number of atoms in 6980 grams of nitrogen, you would first convert the mass of nitrogen to moles using the molar mass of nitrogen (~14 g/mol). Then, you would use Avogadro's number (6.022 x 10^23 atoms/mol) to convert moles to atoms. Overall, the calculation would be 6980 grams of nitrogen * (1 mol / 14 grams) * (6.022 x 10^23 atoms / 1 mol).
To calculate the mass of 2x10^12 atoms of potassium, you first need to find the molar mass of potassium (39.10 g/mol). Then, divide the number of atoms by Avogadro's number to get the moles of potassium. Finally, multiply the moles by the molar mass to find the mass in grams, which in this case would be 0.01566 grams.
To find the number of atoms in 187 grams of calcium, we first need to determine the number of moles of calcium. This is done by dividing the mass (in grams) by the molar mass of calcium (40.08 g/mol). Next, we can use Avogadro's number (6.022 x 10^23 atoms/mol) to calculate the number of atoms in that number of moles.
