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 molecules are in 25.0 g NO2?
4
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
What is O2G?
Most certainly it means: Oxygen molecules ( O2 ) in gaseous state ( O2,g or (O2)g )Note: the letter 'g' should be in subscripted undercase (not Capitalised!)
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.
How many grams of oxygen are needed to react completely with 200.0 g of ammonia NH3?
How many grams of oxygen are needed to react completely with 200.0 g of ammonia, NH3?4NH3(g) + 5O2(g) => 4NO(g) + 6H2O(g)
How many atoms of oxygen are in five molecules of Penicillin G?
The molecular formula for Penicillin G is C16H18N2O4S (Drug Bank). So five molecules would have 20 atoms of oxygen (5 x 4).
How many molecules are in 25.0 g NO2?
4
How many oxygen molecules O2 are in 2.56 grams of O2?
The number of oxygen atoms is 0,188.10e23.
How many molecules of oxygen are produced when a sample of 29.2 g of water is decomposed by electrolysis?
4.88 x 1023 molecules of O2
How many grams are in 5.46x10 to the 24 molecules of diatomic oxygen O2?
5,46x10 to the 24 molecules of diatomic oxygen O2 have a weight of 290,13 g.
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).
How many atoms of oxygen are present in 4.5 g of water?
4.5 g x (6.022 x 1023 molecules / 18.0 g) x (1 atom Oxy / molecule)= 1.5055 x 1023 atoms of Oxygen
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)
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
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
What is the number of molecules in 8 g of oxygen gas?
1) 7 g co 2)16 g so2 3)11 g co2
What is the mass of 0.2 moles of oxygen atoms?
2.000 moles of oxygen atoms weigh 32.00 g. 2.000 moles of oxygen molecules, on the other hand, weigh 64.00 g.
