# What is the molar mass of oxygen g mol?

Answer and Explanation: The molar mass of oxygen is 16 grams per mole (g/mol). The molar mass of an element is calculated by multiplying the element's relative atomic mass by the molar mass constant of 1g/mol. When oxygen's atomic mass of 16 is multiplied by the molar mass constant, the result equals 16 g/mol.

### What is the mass of one mole of oxygen gas?

Oxygen's atomic weight is 16.00 amu. 1 mole of oxygen is 6.02 x 1023 atoms of oxygen 1 amu = 1.661 x 10-24g What is the molar mass (g/mole) of oxygen? Molar mass (in grams) is always equal to the atomic weight of the atom!
• #### What is the mass of one molecule of oxygen?

So the relative atomic mass of oxygen is 16.00, and because an oxygen molecule consists of two atoms of oxygen, you would just multiply this number by 2, and that is your answer. 32 g/mol. So this states that for every 32g of oxygen gas, there would be approximately 6.02 x 10^23 O2 molecules.

22.4 l
• #### How many atoms are in 6.3 mol Zn?

Since we know that there are 6.0221023 atoms in every mole of a substance (Avogadro's Number), there are 6.022E23⋅0.750 atoms of Zn in 0.750 mols of Zn.
B.

### How much does one molecule of oxygen weigh?

Kind of like a "dozen" eggs, but a much bigger number. So anyway, one mole of carbon is the same as 60 trillion trillion carbon atoms and weighs all of 12 grams. Likewise, a mole of hydrogen weighs a paltry 1 gram, and a mole of oxygen tops out at 16 grams.
• #### How many protons neutrons and electrons are in oxygen?

The number eight also means that oxygen has eight protons in the nucleus. The number of protons and the number of electrons are always the same in an element that is neutral and has no charge. Therefore oxygen has 8 electrons. You will find that the atomic weight of oxygen is about 16.
• #### What is the molar mass of oxygen g mol?

Answer and Explanation: The molar mass of oxygen is 16 grams per mole (g/mol). The molar mass of an element is calculated by multiplying the element's relative atomic mass by the molar mass constant of 1g/mol. When oxygen's atomic mass of 16 is multiplied by the molar mass constant, the result equals 16 g/mol.
• #### Is the molar mass the same as the atomic mass?

Molar mass is the mass of one mole - that's 6.022 x 10 - of atoms, or molecules. It must have a unit - typically, grams. When molar mass is given in grams, it has the same numerical value as relative atomic (or molecular) mass.
