Answer 2

Finding Information with Known Density and Mass Fraction

If the density of a substance and its mass fraction are known, it is possible to calculate various properties and characteristics of the substance. The mass fraction, also known as the mass percent, is the ratio of the mass of a component to the total mass of the mixture, expressed as a percentage.

Calculation of Other Properties: - With the known density and mass fraction, it is possible to calculate the mass of the component, the total mass of the mixture, and the volume of the component in the mixture. - The mass fraction can also be used to determine the amount of a specific substance in a given mass of the mixture.

Example Calculation: For example, if the density of a substance is known to be 2 g/cm³ and its mass fraction in a mixture is 20%, the following calculations can be made: - Mass of the component = Density × Volume - Total mass of the mixture = Mass of the component ÷ Mass fraction - Volume of the component in the mixture = Mass of the component ÷ Density

These calculations can provide valuable insights into the composition and characteristics of the substance in question.

Conclusion

Knowing the density and mass fraction of a substance enables the calculation of various properties and characteristics, including the mass of the component, the total mass of the mixture, and the volume of the component in the mixture. These calculations are essential for understanding the composition and behavior of the substance.
