The liquid part of a homogeneous mixture is most often than not the a. solvent
This depends on the type of homogeneous mixture at hand. For a liquid-solid homogeneous mixture, the liquid works as the solvent. For a gas-liquid homogeneous mixture, the liquid often works as the solvent as well. However, for a liquid-liquid homogeneous mixture, the liquid acts as both the solute and solvent.
Answer:
2nd option
Explanation:
Molarity is the number of moles of the solute (NaCl) in 1 litre of the solution (NaCl solution).
Given: concentration= 232g/ L
what we are trying to achieve is __mol/ L.
So in 1 litre, we have 232g of NaCl.
To convert mass to mole, we divide it by the Mr.
Given that the Mr is 58g/mol,
number of moles
= 232 ÷58
= 4
Thus, 1 litre has 4 moles of NaCl.
Therefore, the molarity is 4.0 mol/L.
