133g, 1L,58.5g/mol, What is mol fraction
Didn't ask for molarity but for mole fraction. I assume the mole fraction of the solute and not the solvent. Also, I assume densit of H2O = 1.00 g/mL.
mol fraction = Xsolute = mols solute/total mols
mols solute = 133g/58.5 = ?
mols solvent = 1000g/18 = 55.5
total mols = 55.5 + ?
133g (1 mol/58.5g) = 133/58.5 mols
since it is one liter that is the molarity
Mole fraction, also known as the mole fraction or mole fraction, is a way to express the concentration of a component in a mixture. It is defined as the ratio of the number of moles of a component to the total number of moles in the mixture.
To calculate the mole fraction, you need to know the number of moles of the component of interest and the total number of moles in the mixture.
In your case, you have 133g of the component, the molecular weight of which is 58.5g/mol. To find the number of moles, divide the given mass by the molar mass:
Number of moles = Mass / Molar mass
Number of moles = 133g / 58.5g/mol
Number of moles ≈ 2.27 mol
Now, let's assume you have 1 liter (1L) of the mixture, which contains the component you are interested in. The volume of a solution does not affect the mole fraction calculation because it is a ratio of moles. However, for certain calculations, it can be helpful to know the volume.
Next, you will need to find the total number of moles in the mixture. This is done by adding up the moles of all components present in the mixture. If you only have information about one component, you will consider that as the total number of moles.
In this case, if you have information solely about the component you are interested in, the total number of moles will be the same as the moles of that component, which is 2.27 mol.
Finally, you can calculate the mole fraction by dividing the number of moles of the component of interest by the total number of moles in the mixture:
Mole fraction = Moles of component / Total moles
Mole fraction = 2.27 mol / 2.27 mol
Mole fraction = 1
Therefore, the mole fraction of the component in the mixture is 1, which means it constitutes the entire mixture.
