Answer: Molarity of anions in the chemist's solution is 0.0104 M
Explanation:
Molarity : It is defined as the number of moles of solute present per liter of the solution.
Formula used :
where,
n= moles of solute
= volume of solution in ml = 100 ml
Now put all the given values in the formula of molarity, we get
Therefore, the molarity of solution will be
As 1 mole of gives 2 moles of
Thus moles of
gives =
Thus the molarity of anions in the chemist's solution is 0.0104 M

Explanation:
Given parameters:
Density of ebony wood = 1.174g/ml
Mass of wood = 2.1549lb
Unknown:
Volume of the wood in quarts = ?
Solution:
Density is defined as the mass per unit volume of a substance.
Mass is the quantity of matter the wood contains.
Volume is the space it occupies.
To solve this problem, convert the mass form pounds into grams and plug into the density equation to find volume.
Then convert the volume from mL to quarts.
Density =
Volume =
1 pound = 453.592g
2.1549 lb = 2.1549 x 453.592 = 977.5g
Volume = = 832.6mL
1 quart = 946.353mL
Therefore 832.6mL x = 0.88qt
