If a substance is not chemically pure, it is either a heterogeneous mixture or a homogeneous mixture. If its composition is uniform throughout, it is a homogeneous mixture.
Molar mass NaCl = 58.44 g/mol
number of moles:
mass NaCl / molar mass
145 / 58.44 => 2.4811 moles of NaCl
Volume = 3.45 L
Therefore :
M = moles / volume in liters:
M = 2.4811 / 3.45
M = 0.719 mol/L⁻¹

The atomic number of an element gives the proton and electron in the atom while the mass number gives the total number of protons and neutron
Answer:
Love for Music
Explanation:
This is one example of many non-physical traits. In the womb a mother can listen to her favorite music and the growing baby could grow to like it in the womb!
This is just one of the many other traits that could be passed to their offspring.

It is false that 1 mole of nacl(s) has a greater entropy than 1 mole of nacl (aq).
this is because nacl(aq) is in aqueous state while nacl(s) is in solid state. Nacl(aq) has greater entropy than nacl(s) because in
aqueous state their is increase in entropy. the entropy of the two ions in water has greater entropy than the solid nacl.
