Assuming you mean oxygen gas, the number of molecules can be found by first finding the number of moles = mass of oxygen (4g) / Molecular mass of oxygen gas (32 g mol-1)
This tells us there is 0.125 mol of oxygen gas present.
The number of molecules present is given by the number of moles x the avogadro constant (6.022x10^23)
So the number of oxygen gas molecules present is equal to 0.125 x 6.022x10^23 = 7.5275x10^22 molecules

How many moles and how many molecules are in 64 g of oxygen gas?
1 mole O2 weighs 32 gso 64 g O2 is 2 mol O2 gaswhich has 2 X 6.022 X 1023 = 1.2066 X 1024 molecules of O2
How many molecules are in 25.0 g NO2?
To find the number of molecules in 25.0 g of NO2, you can start by converting the mass to moles using the molar mass of NO2. Then, use Avogadro's number (6.022 x 10^23 molecules/mol) to convert moles to molecules.
What mass of oxygen contain the same number of molecule as 42g of nitrogen?
Both nitrogen and oxygen exist at standard temperature and pressure as diatomic molecules. Therefore, the relative masses of equal numbers of molecules of the substance will the same as the ratios of their atomic masses, which are 15.9994 for oxygen and 14.0067 for nitrogen. The mass of oxygen that contains the same number of molecules as 42 g of nitrogen is 42(15.9994/14.0067) or 48 g, to the justified number of significant digits.
A Sample of a compound contains 64 g of copper and 16 g of oxygen what is the ratio of mass to copper of oxygen?
The ratio of mass of copper to oxygen in the sample is 4:1. This is determined by dividing the mass of copper (64 g) by the mass of oxygen (16 g).
If 75 g of oxygen react how many grams of aluminum are required?
The balanced chemical equation for the reaction between aluminum and oxygen is 4Al + 3O2 → 2Al2O3. Using the stoichiometry of the equation, you would need 50 g of aluminum to react with 75 g of oxygen, since the molar ratio between Al and O2 is 4:3.
How many atoms of oxygen are in five molecules of Penicillin G?
There are 40 atoms of oxygen in five molecules of Penicillin G.
Is oxygen lighter than helium?
no. If it was, we would have oxygen balloons instead of helium balloons.
How many moles and how many molecules are in 64 g of oxygen gas?
1 mole O2 weighs 32 gso 64 g O2 is 2 mol O2 gaswhich has 2 X 6.022 X 1023 = 1.2066 X 1024 molecules of O2
A balloon contains 7.36 g of oxygen gas (O2). How many oxygen molecules are in the balloon?
To find the number of oxygen molecules in the balloon, you can first calculate the number of moles of O2 using its molar mass (32 g/mol). Then, use Avogadro's number (6.022 x 10^23 molecules/mol) to convert moles to molecules. In this case, the balloon contains approximately 1.15 x 10^23 oxygen molecules.
How many molecules of oxygen are produced when a sample of 29.2 g of water is decomposed by electrolysis?
The molar mass of water is 18 g/mol, so 29.2 g is equivalent to 1.62 mol of water. Through electrolysis, each water molecule decomposes into 1 molecule of oxygen and 2 molecules of hydrogen. Therefore, 1.62 mol of water will produce 1.62 mol of oxygen molecules, which is equivalent to 9.73 x 10^23 molecules of oxygen.
How do I calculate the quantity of oxygen that contains same number of molecules as 36 grams of water?
36 g water contain 32 g oxygen.32 g oxygen is equivalent to 1 mol oxygen.1 mol has 6,023.10e23 molecules (or atoms, ions).
You eat 180.0 g of glucose. How many grams of oxygen will you have to breathe in?
To completely metabolize 180.0g of glucose, you would need to breathe in 540.0g of oxygen. This is based on the stoichiometry of cellular respiration, where one molecule of glucose reacts with six molecules of oxygen to produce carbon dioxide and water.
What is the number of molecules in 8 g of oxygen gas?
1) 7 g co 2)16 g so2 3)11 g co2
When 4 g of methane burns it produces 11 g of carbon dioxide and 9 g of water. What mass of oxygen was needed to react with the 4 g of methane?
The needed mass of oxygen is 16 g.
Is the correct equation for the reaction below One molecule of methane gas reacts with two molecules of oxygen gas to form one molecule of carbon-dioxide gas and two molecules of water vapor.?
That's correct: CH(4) + 2O(2) → CO(2) + 2H(2)O However, if there is not enough oxygen available, then 2 molecules of methane will react with 3 molecules of oxygen to produce 2 molecules of [poisonous] carbon monoxide and 2 molecules of water: 2CH(4) + 3O(2) → 2CO + 2H(2)O
What is the chemical equation for acetylene gas C2H2 burns in a welding torch with oxygen to form carbon dioxide gas and water vapor?
2C2H2(g) + 5O2(g) = 2H2O(g) + 4CO2(g) or, 2 Acetylene molecules + 5 Oxygen molecules = 2 water molecules + 4 Carbon dioxide molecules (+ energy)
