When can volume fraction be equal to mole fraction?
The volume fraction of a substance is equal to the mole fraction for ideal gas mixture
Why mole fraction does not dependend upon temperature?
because mole fraction doesnot depend on volume
You multiply any fraction times its reciprocalwhat is the product GIve an example?
You flip it to a fraction
Give an example of an equivalent fraction?
An example is: 3/4 = 9/12
How can you use a model to write a percent as a fraction or write a fraction as a percent and give an example?
% 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%
What is the mole fraction of oxygen in a gas mixture that is 37 percent oxygen and 63 percent nitrogen in volume?
To find the mole fraction of oxygen, first convert the percentages to fractions: 37% oxygen is 0.37 and 63% nitrogen is 0.63. Since the total mole fraction in a mixture is 1, the mole fraction of oxygen would be 0.37/(0.37 + 0.63) = 0.37/1 = 0.37. Therefore, the mole fraction of oxygen in the gas mixture is 0.37.
State relation between mole fraction and Volume fraction?
For Ideal gases, mole fraction=volume fraction
When can volume fraction be equal to mole fraction?
The volume fraction of a substance is equal to the mole fraction for ideal gas mixture
Why mole fraction does not dependend upon temperature?
because mole fraction doesnot depend on volume
What is the mole fraction of oxygen gas in air?
The mole fraction of oxygen gas in air is approximately 0.21. This means that out of every 1 mole of air, 0.21 moles are oxygen gas molecules.
You multiply any fraction times its reciprocalwhat is the product GIve an example?

In what situation can you use only multiplication to find equivalent fractions to a given fraction give an example?
In what situtation can you use only multiplication to find equivalent fraction? Give an example
How do you convert mole fraction to volume fraction of liquid?
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
What is the unit of mole fraction?
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".
What is the mole fraction of phosphoric acid formula weight 98.00 in 175 grams of water formula weight 18.0116?
First, calculate the moles of water: 175g / 18.0116 g/mol = 9.721 moles. The total moles in the solution is the sum of water and phosphoric acid (H3PO4) moles. Next, calculate the mole fraction of H3PO4: moles of H3PO4 / total moles in the solution. This will give you the mole fraction of phosphoric acid in the solution.
