Answer:
A compound is a pure substance that is composed of elements chemically bonded in definite proportions. A compound can be broken down into simpler substances only by chemical reactions, such as electrolysis. A solution is a homogeneous mixture, meaning that it is the same throughout.
Explanation:
.
The wavelength of a sound wave moving at 340 m/s and with a frequency of 256 Hz is calculated using the the below formula
wavelength = speed of the wave/frequency
speed of the wave = 340 m/s
frequency = 256 Hz
wavelength is therefore = 340/256 = 1.32 m

Each ion, or atom, has a particular mass; similarly, each mole of a given pure substance also has a definite mass. The mass of one mole of atoms of a pure element in grams is equivalent to the atomic mass of that element in atomic mass units (amu) or in grams per mole (g/mol).
