I don't recognize the unit "Jo", but I doubt it's convertible into moles.
There is 1 mole present in 1 lb-mole.
1 mole
There are 16 hydrogen atoms in 1 mole of C7H16.
1 mole of CO2 has 1 mole of carbon atoms and 2 moles of oxygen atoms.
The answer depends on the quantity of XeF6
it depends on how many grams of it you are dealing with
No, 1 mole of hydrogen atoms does not equal 1 mole of helium atoms. One mole of any element contains Avogadro's number of atoms (6.022 x 10^23), so 1 mole of hydrogen atoms would have that many hydrogen atoms, while 1 mole of helium atoms would have that many helium atoms.
The molar mass of sulfuric acid (H2SO4) is 98.08 grams/mole. Therefore, there are 98.08 grams in 1 mole of sulfuric acid.
1 mole of any element = 6.02 × 1023 atoms
To convert 1 gram per gram-mole to pounds per pound-mole, you would multiply by 0.00220462.
There is one mole of selenium in one mole of selenium tetrafluoride, as the formula for selenium tetrafluoride is SeF4. Therefore, there is 1 mole of selenium in 1 mole of selenium tetrafluoride.
0.87 grams water (1 mole H2O/18.016 grams)(1 mole O/1 mole H2O)(6.022 X 1023/1 mole O) = 2.9 X 1022 atoms of oxygen --------------------------------------
