How much is a mole?
A mole is equal to 6.022 x 1023. This number is called Avagadros number. A mole is generally abreiviated as "n".
What is 20 percent equal to?
20 percent is equal to 2 over 10
What is percent abundance?
Take percent abundance times atomic mass for each isotope then add all up for average atomic mass.
When will use percent difference and percent error?
When Percent Equal 100%
Is one fourth percent equal to 25 percent?
No, one fourth percent isn't equal to 25 percent. One fourth percent = 1/4% = .25% = .0025.
Is mole percent equal to weight percent?
No, the two concepts are quite unrelated.
How do you find the number of grams in a mole?
If you know the atomic weight of the substance, this is equal to the number of grms in a mole of the stuff!
The atomic ratio is almost equal to the mole ratio of zinc to iron?
Yes.
What is the relationship between the atomic mass of an element and a mole of that element's atom?
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.
Is mole percent of a gas is equal to its volume percent?
Yes - as long as the pressure and temperature are constant.
1 mole equal how many grams of hydrogen?
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.
What is the mass in grams of 1 mole of Na?
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
How does a mole of atoms of one element compare to a mole of another element?
Type your answer here...they all be equal to that element's atomic mass in grams.
If the atomic mass of carbon is 12 amu 1 mole of pure carbon will have a mass of?
12 grams 1 mole is equal to the amu in grams.
One mole of helium gas weighs?
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.
How much does one mole of 0 weigh?
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.
Is the atomic mass unit equal to one mole of a substance?
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.
