It is 100%.
A mole is equal to 6.022 x 1023. This number is called Avagadros number. A mole is generally abreiviated as "n".
No, the unit is "per mole". The number could be atoms or molecules but that is not part of the unit.
No.
Avogadro's number (generally written as 6.02 x 10^23) is the number of atoms or molecules it takes to have one mole of a particular atom or molecule. For example, one mole of Hydrogen is just 6.02 x 10^23 atoms of hydrogen.
For Ideal gases, mole fraction=volume fraction
0.3
The volume fraction of a substance is equal to the mole fraction for ideal gas mixture
The partial pressure is the pressure exerted by just one gas in the mixture.
It is 100%.
0.6
the mole fraction of oxygen= 37/100 0.37 the mole fraction of Nitrogen= .63 that equals to give 1
Mole fraction is dimensionless. It's the amount of moles of species "A" divided by the total amount of moles in the mixture. So "mole A / mole total" equals "dimensionless". To add clarity in the use of mole fractions, one could add as "unit" mole A / mole "mixture".
The total pressure of a gas mixture is the sum of the individual pressures.

0.1 NOPE! the one above is wrong! the answer is 0.3 (I just took it on apex:] )
