A mole is equal to 6.022 x 1023. This number is called Avagadros number. A mole is generally abreiviated as "n".
20 percent is equal to 2 over 10
Take percent abundance times atomic mass for each isotope then add all up for average atomic mass.
When Percent Equal 100%
No, one fourth percent isn't equal to 25 percent. One fourth percent = 1/4% = .25% = .0025.
No, the two concepts are quite unrelated.
If you know the atomic weight of the substance, this is equal to the number of grms in a mole of the stuff!
Yes.
One mole of a substance is equal to the atomic mass of a substance in grams. So, if the atomic mass of sodium is 23, then 1 mole of sodium is approximately 23 grams.
Yes - as long as the pressure and temperature are constant.
By definition, one mole would be the same as the atomic mass. You take the number of moles and multiply it by the atomic mass (divide by one mole for units to cancel). So if you have just 1 mole, the number of grams will be the atomic mass. Hydrogen's atomic mass is 1.007 grams.
The mass in grams of one mole of any element is numerically equal to its atomic weight. The atomic weight of sodium is 22.98976928 so the mass in grams of one mole is 23 grams
Type your answer here...they all be equal to that element's atomic mass in grams.
12 grams 1 mole is equal to the amu in grams.
One mole of any atom has a mass equal to its atomic mass in grams therefore one mole of He has a mass of 4.003 g/mol.
1 mole of O (oxygen) weighs 15. 9996 grams. By definition, 1 mole of any element is equal to its atomic weight expressed in grams. 1 mole is equal to 6.02 x 1023 atoms of that element.
no The mole contain a number of atoms equal to number of atoms in 12 g of carbon-12. The atomic mass unit is equal to one-twelfth the mass of a carbon-12 atom or 1,660538921(73)×10−27 kg.
