There are many different ways to calculate the moles and grams of oxygen. but one mole of oxygen is always gonna equal 32 grams because its diatomic, meaning it only comes in nature as O2. so it would be the Atomic Mass of oxygentimes 2. 16*2= 32
Oxygen gas is composed of diatomic O2 molecules. From the Periodic Table, the atomic weight indicates that the molar mass of oxygen atoms is 16.0g/mole. The diatomic molecule O2 has twice the molar mass as oxygen atoms, and its molar mass is 32g/mole.
The molar mass of oxygen gas (O2) is 32 g/mol. To find the weight of 0.8834 moles of oxygen gas, you would multiply the molar mass by the number of moles: 32 g/mol x 0.8834 mol = approximately 28.27 grams.
Hydrogen gas has the lowest mass per mole, with a molar mass of approximately 2 grams per mole.
No, the (molar) mass (ie. the mass of one mole) is different by factor 2.004:Oxygen atom (O)15.999 g/mole O2,Oxygen molecule (elemental gas, O2) 31.998 g/mole O2Sulfur atom (S) 32.06 g/mole S,Sulfur molecule (bright yellow solid, S8) 256.48 g/mole S8,Sulfur molecule (S2) 64.12 g/mole S2 (there are more than 20 other allotropes)
48. Assuming we can use the ideal gas law PV=nRT, we can see that if pressure and temperature are fixed, a gas will assume a volume proportional to the number of moles of that gas present (R is a constant). Oxygen gas (O2) has a molecular mass of 32, so 1 mole of oxygen has a mass of 32g in that volume, whereas your gas has a mass of 48g (as the volume is fixed, multiply the mass by the density difference) so the molecular weight of your gas is 48 - possibly ozone (O3).
Oxygen gas is composed of diatomic O2 molecules. From the Periodic Table, the atomic weight indicates that the molar mass of oxygen atoms is 16.0g/mole. The diatomic molecule O2 has twice the molar mass as oxygen atoms, and its molar mass is 32g/mole.
32 as oxygen is diatomic
The molar mass of oxygen gas (O2) is 32 g/mol. To find the weight of 0.8834 moles of oxygen gas, you would multiply the molar mass by the number of moles: 32 g/mol x 0.8834 mol = approximately 28.27 grams.
39.95 because that is the molar mass of Argon
The mole fraction of oxygen gas in air is approximately 0.21. This means that out of every 1 mole of air, 0.21 moles are oxygen gas molecules.
Hydrogen gas has the lowest mass per mole, with a molar mass of approximately 2 grams per mole.
To find the number of moles in 16 g of oxygen gas, you need to divide the given mass by the molar mass of oxygen. The molar mass of oxygen (O2) is 32 g/mol. Therefore, 16 g / 32 g/mol = 0.5 moles of oxygen gas.
No, the (molar) mass (ie. the mass of one mole) is different by factor 2.004:Oxygen atom (O)15.999 g/mole O2,Oxygen molecule (elemental gas, O2) 31.998 g/mole O2Sulfur atom (S) 32.06 g/mole S,Sulfur molecule (bright yellow solid, S8) 256.48 g/mole S8,Sulfur molecule (S2) 64.12 g/mole S2 (there are more than 20 other allotropes)
The volume of one mole of oxygen can be estimated by the ideal gas law. In this case, you will use V = nRT/P, where n is the moles of gas, R is the ideal gas constant, T is the temperature in kelvin, P is the system pressure.
16 grams or 32 grams, depending on what you're looking at.The mass of one mole of oxygen atoms is about 16 grams, but oxygen gas exists as a molecule (O2) so 1 mole of (O2) is 32 grams.
To find the number of oxygen atoms in 3.120 grams, we need to first calculate the number of moles using the molar mass of oxygen gas. The molar mass of oxygen gas is 32 g/mol. So, 3.120 grams is equal to 0.0975 moles. Each mole of oxygen gas contains 2 oxygen atoms, so there are 0.195 moles of oxygen atoms in 3.120 grams. Finally, using Avogadro's number (6.022 x 10^23), we find that 1.17 x 10^23 oxygen atoms are present in 3.120 grams of oxygen gas.
Since there are two oxygen molecules, the molar mass would be twice the atomic weight given in the periodic table of elements. O = 16 g/mole O2 = 32 g/mole
