To calculate the number of atoms in 3 moles of potassium nitrate (KNO3), you use Avogadro's number, which is 6.022 x 10^23 atoms/mol. First, calculate the molar mass of KNO3 (101.1 g/mol) then multiply that by 3 to get the total mass in grams. Next, divide the total mass by the molar mass to get the number of moles, and finally multiply the number of moles by Avogadro's number to get the number of atoms. For 3 moles of KNO3, there are approximately 5.4 x 10^24 atoms.
To find the number of atoms in 159g of calcium, you need to first calculate the number of moles of calcium present using the molar mass of calcium. The molar mass of calcium is approximately 40 g/mol. Then, you can use Avogadro's number (6.022 x 10^23 atoms/mol) to convert moles of calcium to atoms. Calculate the number of moles of calcium in 159g using the formula: moles = mass (g) / molar mass (g/mol). Finally, multiply the number of moles by Avogadro's number to determine the number of atoms in 159g of calcium.
To calculate the number of moles in 2.80x10^24 atoms of silicon, you first need to determine the molar mass of silicon, which is approximately 28.0855 g/mol. Next, you can use Avogadro's number, which is 6.022x10^23 atoms/mol, to convert atoms to moles. Divide the number of atoms by Avogadro's number to get the number of moles. Therefore, 2.80x10^24 atoms of silicon is equivalent to approximately 4.65 moles.
