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.
What is the mass of copper if it contains same number of atoms as present in 3.2 grams of sulphur?
To find the mass of copper containing the same number of atoms as in 3.2 grams of sulfur, we first determine the number of moles of sulfur. Sulfur has a molar mass of approximately 32 g/mol, so 3.2 grams corresponds to 0.1 moles of sulfur. Since copper (Cu) has a molar mass of about 63.5 g/mol, the mass of copper that has the same number of moles (0.1 moles) is calculated as 0.1 moles × 63.5 g/mol = 6.35 grams. Therefore, the mass of copper is 6.35 grams.
How many atoms are present in 16g of o and 8g pf sulphur?
To find the number of atoms in 16 g of oxygen (O), we first determine the number of moles: 16 g of O divided by its molar mass (approximately 16 g/mol) gives 1 mole of O, which contains about 6.022 x 10²³ atoms. For 8 g of sulfur (S), the molar mass is approximately 32 g/mol, so 8 g corresponds to 0.25 moles, equating to about 1.505 x 10²³ atoms of S. In total, there are approximately 7.527 x 10²³ atoms from both elements combined.

How much mass is in 1 mole of sulfur atoms?
Remember the Equation Moles = mass(g) / Ar (Relative Atomic Mass) Algebraically rearranging mass(g) = moles X Ar We have 1 mole and from the Periodic Table the Atomic Mass of Sulphur is '32'. Hence substituting mass(g) = 1 moles X 32 mass = 32 g .
How many moles of phosphorus atoms are there in 8 moles of P4O10?
Since 14 (4+10) moles of P4O10 contains 4 moles of Phosphorus, 8 moles of P4O10 will contain :: (8 x 4)/14 = 2.286 moles of Phosphorus
The mass of oxygen which contains the same number of atoms as those present in 64 grams of sulfur is?
The gram-atomic mass of sulphur is 32 and that of oxygen is 16, to two significant digits. Therefore, the mass of oxygen with the same number of atoms as 64 grams of sulphur can be found from the proportion m/64 = 16/32, or m = 32 grams.

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.
How many atoms are in 64 g sulfur?
2(6.02 x 10^23) atoms
How many grams atoms are in 100 of sulfur?
The molar mass of sulfur is approximately 32 grams per mole. Therefore, 100 grams of sulfur would contain approximately 3 moles of sulfur atoms (100 grams / 32 grams/mole). To find the number of atoms, you would then multiply the number of moles by Avogadro's number (6.022 x 10^23 atoms/mole) to get the total number of sulfur atoms in 100 grams.
How many hydrogen atoms in 2 moles of hydrochloric acid?
In 2 moles of hydrochloric acid (HCl), there are 2 moles of hydrogen atoms. Since each molecule of HCl contains one hydrogen atom, multiplying the moles of HCl by Avogadro's number (6.022 x 10^23) gives the number of hydrogen atoms. Therefore, there are 1.204 x 10^24 hydrogen atoms in 2 moles of HCl.
How many atoms are present in 8g of S?
To determine the number of atoms in 8g of sulfur (S), you would first calculate the number of moles using the molar mass of sulfur (32 g/mol). Then, using Avogadro's number (6.022 x 10^23), you can convert the moles to atoms.
What is the mass of copper if it contains same number of atoms as present in 3.2 grams of sulphur?
To find the mass of copper containing the same number of atoms as in 3.2 grams of sulfur, we first determine the number of moles of sulfur. Sulfur has a molar mass of approximately 32 g/mol, so 3.2 grams corresponds to 0.1 moles of sulfur. Since copper (Cu) has a molar mass of about 63.5 g/mol, the mass of copper that has the same number of moles (0.1 moles) is calculated as 0.1 moles × 63.5 g/mol = 6.35 grams. Therefore, the mass of copper is 6.35 grams.
How many atoms are there in 32 g of sulfur?
To calculate the number of atoms in 32g of sulfur, you first need to determine the number of moles of sulfur in 32g. Then, use Avogadro's number (6.022 x 10^23 atoms/mol) to convert moles to atoms. The final result will provide the number of sulfur atoms in 32g of sulfur.
