The molar mass of sulfur is approximately 32.06 grams/mol. Therefore, 1 mol of sulfur atoms will have a mass of 32.06 grams.
There are 1 mol of oxygen atoms in 1 mol of CO2. Therefore, in 0.5 mol of CO2, there are 0.5 mol of oxygen atoms. Number of molecules = 0.5*6.022 *10^23 ≈ 3.011 *10^23 molecules
We first need to determine the number of moles in 50.0g of diatomic oxygen using its molar mass. The molar mass of O2 is 32.0 g/mol. Therefore, 50.0g of O2 is equivalent to 50.0g / 32.0 g/mol = 1.56 mol. Since there are 2 atoms of oxygen in every molecule of O2, we can calculate the number of atoms in 50.0g of O2 by multiplying the number of moles by Avogadro's number: 1.56 mol * 6.022 x 10^23 atoms/mol = 9.33 x 10^23 atoms.
Carbon monoxide, CO, has one atom of carbon and one atom of oxygen. The molar mass of carbon is 12.0107 g mol-1 and the molar mass of oxygen is 15.9994 g mol-1, so the molar mass of CO is 28.0101 g mol-1.
Ans:Quartz is SiO2. It has a formula weight of 60.1 g/mol. 3 grams of SiO2 is 0.05 moles.Each mole of SiO2 has 0.1 moles of oxygen since there are 2 oxygen atoms per formula unit of SiO2.(1 mole of anything is 6.02x1023 of anything.)0.1 mol oxygen atoms x 6.02x1023 oxygen atoms / mol oxygen atoms= 6.02 x 1022 oxygen atoms.Number of O atoms =6.02×1022
The mass of 2.000 mol of oxygen atoms is 32.00 grams.
moles = mass/molar mass The molar mass of an oxygen atom = 16 g mol-1, as there are two oxygen atoms in diatomic oxygen this has to be doubled. 42g / 32g mol-1 = 1.3125 moles
The molar mass of sulfur is approximately 32.06 grams/mol. Therefore, 1 mol of sulfur atoms will have a mass of 32.06 grams.

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.
The atomic mass is grams/mole So when you have e.g. 12 grams of carbon which has atomic mass = 12, you have one mole. ( Avogadro's number is one mole: 6.02×10²³ )
The mass of one mole of atoms is equal to the atomic mass of the element expressed in grams. This is known as the molar mass. For example, the molar mass of carbon (C) is 12 grams per mole, of oxygen (O) is 16 grams per mole, and so on.
We first need to determine the number of moles in 50.0g of diatomic oxygen using its molar mass. The molar mass of O2 is 32.0 g/mol. Therefore, 50.0g of O2 is equivalent to 50.0g / 32.0 g/mol = 1.56 mol. Since there are 2 atoms of oxygen in every molecule of O2, we can calculate the number of atoms in 50.0g of O2 by multiplying the number of moles by Avogadro's number: 1.56 mol * 6.022 x 10^23 atoms/mol = 9.33 x 10^23 atoms.

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.
