The mass of a NaCl solution that is required to prepare 0.40 L of a 0.75 M solution is 17.55g. Details about mass can be found below.
<h3>How to calculate mass?</h3>
The mass of a substance can be calculated by multiplying the number of moles by its molar mass.
However, the number of moles of a solution must be initially calculated by using the following formula:
molarity = no of moles ÷ volume
no of moles = 0.75 × 0.40
no of moles = 0.3 moles
mass of NaCl = 0.3 × 58.5 = 17.55g
Therefore, the mass of a NaCl solution that is required to prepare 0.40 L of a 0.75 M solution is 17.55g.

Answer:
B. because there is two equations just like commutative property in math its the same thingish
Explanation:
cesium sulfate solubility decreases with decrease in temperature (answer C) change in temperature led to the change in kinetic energy.The lower kinetic energy the lower the solubility.Decrease in temperature led to lower kinetic energy hence lowering the solubility.
Answer 12.2g is the answer
