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.
I assume you mean the molecular mass. The diatomic oxygen's molecular mass is 32g/mol. The element is 16 (or 15.9994 to be exact) g/mol
The molar mass of oxygen gas (O2) is 32. If you look on the Periodic Table of elements the numbers underneath the symbols for the elements are their molar mass in grams
32.0 g mol-1
Molar is a type of tooth
Its molar mass is 32 grams
Molar mass of oxygen is 16 g/mol.
To find the percent composition of oxygen in Na2O, find the total molar mass of the compound. Then, divide the molar mass of oxygen by the molar mass of the compound, and multiply by 100% to get the percent oxygen.
Ozone contains 3 molecules of oxygen. Molar mass of ozone is 48.
Sodium has a molar mass of 23 Hydroxide (Hydrogen & Oxygen) have a molar mass of 17 23+17=40g/mol 40grams per mole
The molar mass of the lightest alcohol, methanol, is 32.04 grams per mol. No alcohol has a molar mass of 4.75 grams. To find the molar mass of a substance, you sum the mass of every atom that makes up your compound. For methanol, you add the mass of three hydrogens, a carbon, and an oxygen atom. An alcohol group, more properly a "hydroxyl," consists of an oxygen and a hydrogen and contributes about 17 grams per mol to the molar mass (about 16 g/mol for an oxygen atom and 1 for a hydrogen). Hope this helps!
Molar mass is the mass per amount substance .What you need to do is just add the mass of everything . For ex -mass of siver -107 mass of nitrogen -14 mass of oxygen -16 x 3=48(there are three atoms of oxygen ) Molar Mass of AgNO3 - 107+14+48=169 mols You can include decimals also as per the periodic table .
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.
To find the percent composition of oxygen in Na2O, find the total molar mass of the compound. Then, divide the molar mass of oxygen by the molar mass of the compound, and multiply by 100% to get the percent oxygen.
Ozone contains 3 molecules of oxygen. Molar mass of ozone is 48.
The molar mass of CO2 is Mr (C)=12.01 Mr (0)=16.00 Therefore, the molar mass is (12.01+(16.00x2) since there are 2 oxygen atoms then the molar mass will be doubled for oxygen therefore, Molar Mass=48.01 g/mol
32
Molar mass of all oxygen in compound/Total molar mass of compound * 100 = % oxygen in compound ==================
Sodium has a molar mass of 23 Hydroxide (Hydrogen & Oxygen) have a molar mass of 17 23+17=40g/mol 40grams per mole
moles = mass/molar mass The molar mass of an oxygen atom = 16 g mol-1, as there are two oxygen atoms in diatomic oxygen this has to be doubled. 42g / 32g mol-1 = 1.3125 moles
The molar mass of an element is its atomic weight in grams. The molar mass of a molecule or compound is the sum of the subscripts times the molar masses in grams. For example, the molar mass of hydrogen, H, is 1.00794g and the molar mass of oxygen, O, is 15.9994g. The molar mass of water, H2O, is (2 x 1.00794g) + (1 x 15.9994g O) = 18.01528g.
The molar mass of the lightest alcohol, methanol, is 32.04 grams per mol. No alcohol has a molar mass of 4.75 grams. To find the molar mass of a substance, you sum the mass of every atom that makes up your compound. For methanol, you add the mass of three hydrogens, a carbon, and an oxygen atom. An alcohol group, more properly a "hydroxyl," consists of an oxygen and a hydrogen and contributes about 17 grams per mol to the molar mass (about 16 g/mol for an oxygen atom and 1 for a hydrogen). Hope this helps!
Lithium has a molar mass of 6.94 g/mol. Oxygen has a molar mass of 16.00 g/mol. Since Lithium Oxide has 2 Lithium atoms, the molar mass is: (6.94 x 2) + 16.00 = 29.88 g/mol.
Molar mass is the mass per amount substance .What you need to do is just add the mass of everything .
