10 to the power of 7?
The volume fraction of a substance is equal to the mole fraction for ideal gas mixture
because mole fraction doesnot depend on volume
You flip it to a fraction
An example is: 3/4 = 9/12
% to fraction: divide % by 100%Example: 3% = 3%/100% = 3/100fraction to 100%: multiply the fraction by 100%Example: 3/100 =3/100 * 100% = 3%
the mole fraction of oxygen= 37/100 0.37 the mole fraction of Nitrogen= .63 that equals to give 1
For Ideal gases, mole fraction=volume fraction
The volume fraction of a substance is equal to the mole fraction for ideal gas mixture
because mole fraction doesnot depend on volume
The mole fraction of Oxygen = 21/100= .21
The mole fraction of HCl is 0.34.

In what situtation can you use only multiplication to find equivalent fraction? Give an example
You need the balanced symbol equation for the reaction. The numbers in front of the formulae show the mole ratios. For example, in the thermal decomposition of calcium carbonate: CaCO3 --> CaO + CO2 The equation is balanced. The mole ratio between CaCO3 and CO2 is 1:1 because there is 1 mole of CaCO3 for every mole of CO2
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".
