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

∙ 7y agoYou need to distinguish between oxygen gas and atmospheric oxygen. Oxygen gas is 16 grams per mole, while atmospheric oxygen (O2) has twice the amount of oxygen and, therefore, weighs 32 grams.

What is the molar mass of oxygen gas?
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.
What is the weight of 0.8834 mole oxygen gas?
Oxygen has a molar mass of 16 grams per mole 1 mole = 16 grams 0.8834 mole = x grams x=14.1344 grams
Is the mass of 1 mole of oxygen and 1 mole of S same?
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)
What is the molar mass of a gas if 1.10g of the gas has a volume of 245mL at STP?
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).
Which gas has the lowest mass per mole?
Hydrogen
What is the molar mass of oxygen gas?
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.
What is the weight of 0.8834 mole oxygen gas?
Oxygen has a molar mass of 16 grams per mole 1 mole = 16 grams 0.8834 mole = x grams x=14.1344 grams
What is the mass of 1 mole of O2?
32 as oxygen is diatomic
How much does a mole of diatomic oxygen weigh?
1 mole of a pure substance has a mass equal to its molecular mass (MM) so 1 mole of a substance x MM with oxygen its molar mass is 15.9994 so if your trying to find HALF then the equation would be 0.5 x 15.9994 therefore half a mole of oxygen gas will weigh exactly 7.9997 grams approx 8grams google usually helps with these sorts of equations aswell Love Maddi Leicester
What is the molar mass of oxygen gas 02?
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
Is the mass of 1 mole of oxygen and 1 mole of S same?
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)
What is the mole fraction of oxygen gas in air?
The mole fraction of Oxygen = 21/100= .21

48.

How many liters are in a mole of oxygen?
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.
The molar mass of a gas can be determined from?
for Apex: can be found easily from the periodic table is the mass of a mole of the gas
How many atoms of oxygen are in 3.120 grams of oxygen gas?
3.120 grams oxygen gas (1 mole O2/32 grams)(6.022 X 1023/1 mole O2) = 5.871 X 1022 atoms of oxygen gas ------------------------------------------------
Molar mass of oxygen?
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.
