The student would find the water and sand, because salt dissolves in water unless it was ocean water or sea water
The new concentration of sodium phosphate is 0.315 mol·L⁻¹.
We can use the dilution formula
:
<em>c</em>₁<em>V</em>₁ = <em>c</em>₂<em>V</em>₂
We can rearrange the formula to get
<em>c</em>₂= <em>c</em>₁ × (<em>V</em>₁/<em>V</em>₂)
∴ <em>c</em>₂ = 1.50 mol·L⁻¹ × (21.00 mL)/(100.0 mL)] = 1.50 mol·L⁻¹ × 0.2100
= 0.315 mol·L⁻¹
Answer:
Clear communication
Explanation:

<span> It is essential that the standard solution, in this case NaOH, must be prepared daily because a standard has to have a high percentage purity. Aside from high purity, standards should also have accurate measurements. If we will use the same standard solution, there is a great tendency for the solution to get contaminated. In turn, readings using this solution will no longer be accurate.</span>
