Answer:
1.26 × 10^-8 M
Explanation:
We are given;
Number of moles of mercury (i) chloride as 0.000126 μmol
Volume is 100 mL
We are required to calculate the concentration of the solution.
We need to know that;
Concentration is also known as molarity is given by;
Molarity = Number of moles ÷ Volume
Number of moles = 1.26 × 10^-10 Moles
Volume = 0.01 L
Therefore;
Concentration = 1.26 × 10^-10 Moles ÷ 0.01 L
= 1.26 × 10^-8 M
Thus, the molarity of the solution is 1.26 × 10^-8 M

Answer:
17.5 g/cm³
Explanation:
We can solve this particular problem by keeping in mind the <em>definition of density</em>:
As the problem gives us both <em>the mass and the volume</em> of the box, we can now proceed to <u>calculate the density</u>:
The density of the box is 17.5 g/cm³.
