I think you would take the 6 billion atoms and divide it by Avogadro's number which is the number of atoms in a mole of a element by definition.
I don't remember the value of that number but someone will.
382 g Co contain 6,482 moles.
To find the number of moles, we need to divide the given mass of cobalt (382g) by its molar mass, which is approximately 58.93 g/mol. Therefore, 382g of cobalt contains approximately 6.48 moles of atoms.
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.

To determine the number of moles in 382 g of cobalt (Co), first calculate the molar mass of cobalt, which is approximately 58.93 g/mol. Then, divide the given mass by the molar mass to obtain the number of moles. Moles = 382 g / 58.93 g/mol = approximately 6.48 moles of Co atoms.
4,54 L of CO have 0,182 moles.
If you have 0.5 moles of K₂CO₃, then you simply have 0.5 moles of K₂CO₃. The quantity of moles is a direct measurement, so there are no additional calculations needed. Therefore, the answer is 0.5 moles of K₂CO₃.
To find the number of oxygen atoms in 7 grams of carbon monoxide (CO), first calculate the molar mass of CO, which is approximately 28 g/mol (12 g/mol for carbon and 16 g/mol for oxygen). In 7 grams of CO, there are about 0.25 moles (7 g ÷ 28 g/mol). Since each molecule of CO contains one oxygen atom, this corresponds to 0.25 moles of oxygen atoms, which equals approximately 1.51 x 10²³ oxygen atoms (0.25 moles × 6.022 x 10²³ atoms/mole).
The answer is 10 moles of carbon monoxide.2 C + O2 = 2 CO
To determine the number of moles of oxygen needed to react with 4.52 moles of carbon monoxide (CO), we refer to the balanced chemical equation for the reaction: 2 CO + O₂ → 2 CO₂. From the equation, 2 moles of CO react with 1 mole of O₂. Therefore, to find the moles of O₂ required, we can use the ratio: (4.52 moles CO) × (1 mole O₂ / 2 moles CO) = 2.26 moles of O₂. Thus, 2.26 moles of oxygen are needed to react with 4.52 moles of CO.
If 1 mole of carbon reacts, 1 mole of CO is produced according to the balanced chemical equation for the reaction. Therefore, if 1.4 moles of carbon react, 1.4 moles of CO will be produced.
To find the number of moles of CO molecules in 52g of CO, we first need to determine the molar mass of CO, which is approximately 28 g/mol. Then, we divide the given mass by the molar mass to get the number of moles. So, 52g of CO is equivalent to approximately 1.86 moles of CO molecules.
