Moles of a Substance and the Molecular Weight The mass of oxygen equal to one mole of oxygen is 15.998 grams and the mass of one mole of hydrogen is 1.008 g.
How many mole is o?
One mole
One mole of oxygen atoms contains 6.02214179×1023 oxygen atoms. Also, one mole of nitrogen atoms contains 6.02214179×1023 nitrogen atoms….Applications of the Mole.

| Mass of substance (g) | 1/Molar mass (mol/g) × Avogadro’s constant (atoms/mol)) | Atoms (or molecules) |
What is the molar mass of O in g mol?
16.00 g/mol.
For example, the atomic mass of an oxygen atom is 16.00 amu; that means the molar mass of an oxygen atom is 16.00 g/mol.
How many moles of oxygen are in C9H8O4?
Calculate the number of oxygen atoms in 0.480 g of aspirin, C9H8O4.
How many liters are in 1 mole of O2?
22.4 liters
The molar volume of an ideal gas is ~22.4 liters per mole (we’ll consider O2 to be an ideal gas for these purposes, and 22.4 is an approximation that varies with temperature, it’s 22.414 at 0C).
How many grams does o have?
If you look in your periodic table, the molar mass (is the atomic weight) of Oxygen is 16.0 g/mol. Since there are 2 atoms in O2 , you have to multiply the number of atoms provided by the molar mass of each atom.
How do you calculate Avogadro’s number?
The best estimate of the charge on an electron based on modern experiments is 1.60217653 x 10-19 coulombs per electron. If you divide the charge on a mole of electrons by the charge on a single electron you obtain a value of Avogadro’s number of 6.02214154 x 1023 particles per mole.
What is the weight of O?
15.999 u
Oxygen/Atomic mass
What is the mass of oxygen in C9H8O4?
180.15 amu
Likewise, the molecular mass of an aspirin molecule, C9H8O4, is the sum of the atomic masses of nine carbon atoms, eight hydrogen atoms, and four oxygen atoms, which amounts to 180.15 amu (Figure 3.3).
How many atoms are in C9H8O4?
For example, in a molecule of aspirin, C9H8O4, there are 9 carbon atoms, 8 hydrogen atoms and 4 oxygen atoms. compound. For example, one mole of aspirin contains 9 moles of carbon atoms, 8 moles of hydrogen atoms and 4 moles of oxygen atoms.
