Let’s use the formula for finding the mass fraction of a substance:
w (r.v.) = (m (r.v.) * 100%) / m (r-ra)
From here we find the mass of the solution:
m (r-ra) = (m (r.v.) * 100%) / w (r.v.)
m (solution) = (4580 g * 100%) / 25% = 18320 g
We find the density of a substance by the formula:
p = m / V = 18320 g / 10 ml = 1832 g / mol
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.
