The number of grams in a mole of a molecule is found by looking at the Atomic Mass of each element on the Periodic Table. The molar mass of an element is it's atomic mass in grams. The atomic mass of oxygen is 15.999. Since there are two atoms of oxygen in a molecule of oxygen, the molar mass of oxgen (O2) is 15.999 x 2. That comes out to 31.998g/mol, or you can round to 32 if significant figures arn't important to you.

∙ 11y agoA mole is the measument of a single, in this case oxygen molecule. Oxygen on the periodic table is shown like this 8 O 16.00 The 16 is showing the atomic mass. So to answer the question above the answer is ... There are 1,600 moles in 100 grams of oxygen

∙ 11y agoOxygen at standard temperature and pressure exists as diatomic molecules. Therefore, the gram molecular mass of oxygen gas is twice the atomic mass of oxygen, or about 32 grams. Therefore, 32 g of oxygen gas constitutes 1.0 moles of oxygen, to the justified number of significant digits.

∙ 15y agoFor this you need the atomic (molecular) mass of O2. Take the number of moles and multiply it by the atomic mass. Divide by one mole for units to cancel.
2.00 moles O2 × (32.0 grams) = 64.0 grams O2

How many liters of oxygen gas are present in 11.3 grams of oxygen gas?
Because oxygen gas (O2) has a molar mass of 32g/mol, 11.3 g * 1/32 mol/g gives about .35 moles. An ideal gas has a volume of 22.4 L/mol at STP, so 11.3 g O2 would have a volume of 7.91 L at STP.
How many moles of oxygen are represent in 0.16 g of oxygen gas?
using the equation moles=mass/molar mass (since its in gas form) O2 => 16*2 =32 0.16/32=0.005 moles :)
How many moles of oxygen gas are needed to react with 10.0 mol of ammonia?
4NH3 + 3O2 -----> 2N2 + 6H2O 4 moles of ammonia react with 3 of oxygen. So 10 moles of ammonia requires 7.5 moles of oxygen.
How many moles of potassium chlorate must be used to produce 6 moles of oxygen gas?
2KClO3 --> 2KCl + 3O2For every 3 moles of oxygen gas produced, 2 moles of potassium chlorate are used.6 moles O2 * (2 moles KClO3 reacted / 3 moles O2 produced) = 4 moles KClO3
How many oxygen atoms are present in 40.0 grams of oxygen gas?
Ar of O = 16g/mol Mr of O2 = 2(16) = 32g/mol Using the formula : Number of moles = mass / Mr Number of moles = 40g / 32g/mol = 1.25mols One mole of substance contains the same number of particles as the Avogadro constant, which is 6.02 x 10^23 Number of Oxygen molecules = 1.25 x 6.02 x 10^23 = 7.525 x 10^23 Each Oxygen molecules contain two Oxygen atoms Number of Oxygen atoms = 7.525 x 10^23 = 1.505 x 10^24 atoms
How many grams of O2 are in 50moles of the oxygen gas?
Ar of O = 16g/mol Mr of O2 = 2(16) = 32g/mol Using the formula : mass = Mr x number of moles mass = 32g/mol x 50mols = 1600g
How many moles are in 5.56g of oxygen gas (O2)?
The answer is 0,173 moles.
How many moles of oxygen gas react with 0.100 mol of pentane C5H12?
The answer is 0,8 moles oxygen.
How many grams are in 6.5 moles of oxygen gas?
6,5 moles oxygen equals 208 g.
How many liters of oxygen gas are present in 11.3 grams of oxygen gas?
Because oxygen gas (O2) has a molar mass of 32g/mol, 11.3 g * 1/32 mol/g gives about .35 moles. An ideal gas has a volume of 22.4 L/mol at STP, so 11.3 g O2 would have a volume of 7.91 L at STP.
How many moles of oxygen gas are there in 135 liters of oxygen at Standard Temerature Pressure?
The equivalent in moles is 6,03.
How many moles of oxygen gas O2 are in 64 grams of O2?
The answer is 2 moles.
Which is more heavier - hydrogen gas or oxygen gas?
Mass of Hydrogen gas:- 2g/mol Mass of Oxygen gas :- 32g/mol Therefore, Oxygen gas is more heavier
What is the mass of 0.2 moles of oxygen gas?
The mass of 0,2 moles of oxygen gas is 6,4 g.
How many grams of oxygen are needed to react with 2.5 grams of dihydrogen sulfide?
Sulfur dioxide is SO2, so there are 2 moles of oxygen for each mole of sulfur. In 25 moles of SO2, there are 25 moles of S, so there must be 50 moles of oxygen, or 25 moles of diatomic oxygen gas (O2).
How many no of moles are there in 16 gm of oxygen gas?
1 mole.
How many moles are in 68.5 liters of oxygen gas at STP?
3.058
