Use equation density = mass/volume
Known/Given
d= 10.5g/cm^3
v= 24.0 cm^3
Use that equation i just mentioned...
Solution
Rewrite the formula as the forumla for solving density into mass
Which is... mass = 10.5g/cm^3 × 24.0cm^3 = 252g
So thats the answer
252g
Hope i could help
Energy levels are the electron shells where electrons are found at a fixed distance from the nucleus of the atom. The atom could emit 6 different wavelengths.
<h3>What is wavelength?</h3>
A wavelength is a distance between the adjacent crests in wave signals propagated in a system. Wavelength
is in inverse relation to the frequency of the wave.
When an electron jumps from energy level 1 to 2, 1 to 3, and 1 to 4 one wavelength each is present. Hence, making the total wavelength to be 3, in transition from the first energy level.
Similarly, from energy levels, 2 to 3 and 2 to 4, a total of 2 wavelengths, and from energy levels 3 to 4 one wavelength is produced.
So the total different wavelengths of the radiation that can be emitted will be 3 + 2 + 1 = 6.
Therefore, 6 different wavelengths of radiation will be emitted by the atom.

Answer:
Scandium(III) fluoride, ScF3, is an ionic compound. It is slightly soluble in water but dissolves in the presence of excess fluoride to form the ScF63− anion.
