How many atoms of O are in 3.65 mol of sucrose?
Sucrose has a chemical formula of C12H22O11, so it contains 11 oxygen atoms per molecule. In 3.65 mol of sucrose, the number of molecules can be calculated using Avogadro's number, and then multiplied by the number of oxygen atoms per molecule to find the total number of oxygen atoms. Therefore, in 3.65 mol of sucrose, there are 2.45 x 10^24 oxygen atoms.
How many O atoms are in 3.15 mol of SnO2?
There are approximately 3.02 x 10^24 oxygen atoms in 3.15 mol of SnO2. This is calculated by multiplying Avogadro's number (6.022 x 10^23) by the number of moles of oxygen atoms in SnO2 (2 moles of oxygen per 1 mole of SnO2).
How many atoms are present in 16g of O and 8g of S?
To calculate the number of atoms present in a given mass of a substance, we need to use the concept of molar mass and Avogadro's number. The molar mass of oxygen (O) is approximately 16 g/mol, and the molar mass of sulfur (S) is approximately 32 g/mol. For oxygen: 16g / 16 g/mol = 1 mol of O. 1 mol of O contains 6.022 x 10^23 atoms (Avogadro's number). Therefore, 16g of O contains 6.022 x 10^23 atoms. For sulfur: 8g / 32 g/mol = 0.25 mol of S. 0.25 mol of S contains 0.25 x 6.022 x 10^23 atoms = 1.5055 x 10^23 atoms. Therefore, there are approximately 6.022 x 10^23 atoms in 16g of oxygen and approximately 1.5055 x 10^23 atoms in 8g of sulfur.

How many atoms in 16g of O and 8g of S?
In 16g of O, there are approximately 3.02 x 10^23 atoms, as the atomic mass of oxygen is 16 g/mol. In 8g of S, there are approximately 6.02 x 10^23 atoms, as the atomic mass of sulfur is 32 g/mol.
How many atoms are in 16 grams of oxygen?
1mol O = 16.0g (rounded to 1 decimal place) 1mol O atoms = 6.022 x 1023 atoms 16g O x 1mol/16g = 1mol O 1mol O x 6.022 x 1023atoms/mol = 6.022 x 1023 atoms O
Calculate the number of atoms of O contained in 16.0 pounds of O?
To calculate the number of oxygen atoms in 16.0 pounds of oxygen, first convert 16.0 pounds to grams (1 pound ≈ 453.592 grams). Then, calculate the number of moles of oxygen using the molar mass of oxygen (16.00 g/mol). Finally, use Avogadro's number (6.022 x 10^23 atoms/mol) to find the number of oxygen atoms.
How many atoms are in Ba OH 2?
1 mol Ba X (137.33 g Ba / mol Ba) = 137.33 g Ba2 mol O X (16.00 g O / mol O) = 32.00 g O2 mol H X (1.01 g H / mol H) = 2.02 g HMolar mass of Ba(OH)2 = 171.35 g/mol
How many atoms are in 0.700g of P2O5?
To find the number of atoms in 0.700 g of P₂O₅, first calculate the molar mass of P₂O₅, which is approximately 142.0 g/mol (with phosphorus at about 31.0 g/mol and oxygen at about 16.0 g/mol). Next, determine the number of moles in 0.700 g by dividing by the molar mass: 0.700 g / 142.0 g/mol ≈ 0.00493 moles. Since each formula unit of P₂O₅ contains 7 atoms (2 phosphorus and 5 oxygen), multiply the moles by Avogadro's number (approximately (6.022 \times 10^{23}) atoms/mol) to find that there are roughly (1.48 \times 10^{21}) atoms in 0.700 g of P₂O₅.

How many moles of O atoms are present in a 254g sample of carbon dioxide?
To find the number of moles of oxygen atoms in a 254 g sample of carbon dioxide (CO₂), first calculate the molar mass of CO₂, which is approximately 44 g/mol (12 g/mol for carbon and 32 g/mol for two oxygen atoms). The number of moles of CO₂ in the sample is 254 g ÷ 44 g/mol = about 5.77 moles. Since each molecule of CO₂ contains two oxygen atoms, the total number of moles of oxygen atoms is 5.77 moles × 2 = approximately 11.54 moles of O atoms.
