How many atoms are in 64 grams of sulfur?
To calculate the number of atoms in 64 grams of sulfur, you first need to determine the molar mass of sulfur (32 g/mol). Then, you divide the given mass by the molar mass to find the number of moles (64 g / 32 g/mol = 2 mol). Finally, you use Avogadro's number (6.022 x 10^23) to find the number of atoms in 2 moles of sulfur, which would be 2 mol x 6.022 x 10^23 atoms/mol.
How many argon (Ar) atoms are there in 1.5 102 g of argon?
To find the number of argon atoms, we first need to determine the molar mass of argon: 39.95 g/mol. Next, we convert the given mass to moles using the molar mass: 1.5 x 10^2 g / 39.95 g/mol = 3.75 mol. Finally, we use Avogadro's number (6.022 x 10^23 atoms/mol) to find the number of atoms: 3.75 mol x 6.022 x 10^23 atoms/mol ≈ 2.26 x 10^24 argon atoms.
Calculate the number of atom in 13.2 mol copper?
To calculate the number of atoms in 13.2 mol of copper, you can use Avogadro's number, which is approximately 6.022 x 10^23 atoms per mole. Multiply 13.2 mol by Avogadro's number to get the number of atoms: 13.2 mol * (6.022 x 10^23 atoms/mol) = 7.93 x 10^24 atoms. Therefore, there are approximately 7.93 x 10^24 atoms in 13.2 mol of copper.
How many atoms of palladium (Pd) is 400 g of palladium?
To find the number of atoms in 400 grams of palladium (Pd), first determine the molar mass of palladium, which is approximately 106.42 g/mol. Then, divide 400 g by the molar mass to find the number of moles: ( 400 , \text{g} \div 106.42 , \text{g/mol} \approx 3.76 , \text{mol} ). Finally, multiply the number of moles by Avogadro's number ((6.022 \times 10^{23} , \text{atoms/mol})) to find the total number of atoms: ( 3.76 , \text{mol} \times 6.022 \times 10^{23} \approx 2.26 \times 10^{24} ) atoms of palladium.
