How to find the mass of a solute if you know the volume of the solution and the mass fraction in percent?
| November 22, 2020 | education
Mass fraction – the ratio of the mass of the solute to the mass of the solution, measured in percent (the result must be multiplied by 100%) or in mass fractions (there are no units of measurement).
From the definition, the formula is compiled:
ω in-va = m in-va * 100% / m solution (ω in%);
ω in-va = m in-va / m solution (ω in mass fractions).
From this formula we deduce how to find the mass of the solute:
m in-va = ω in-va * m solution / 100% (ω in%);
m in-va = ω in-va * m solution (ω in mass fractions).
One of the components of a person's success in our time is receiving modern high-quality education, mastering the knowledge, skills and abilities necessary for life in society. A person today needs to study almost all his life, mastering everything new and new, acquiring the necessary professional qualities.
