8. What is the molarity of a CsOH solution if 30.0 mL of the solution is neutralized by 26.4 mL 0.25 M HBr solution (Hint: Ma x Va = Mb x Vb. Rearrange to solve for Mb)?
Ma = Molarity of Acid (M – mol/L)
Va = Volume of Acid (mL needs to be converted to L)
Mb = Molarity of Base (M – mol/L)
Vb = Volume of Base (mL needs to be converted to L)
CsOH = Base = What’s the molarity of the Base? = Mb
HBr = Acid = What’s the molarity of the acid? = Ma
Does the problem give you a volume for the acid? = Va
Does the problem give you a volume for the base? = Vb

HBr + CsOH = CsBr + H2O

0.22M

Explanation:

The equation for the reaction is given below:

HBr + CsOH —> CsBr + H2O

From the above, the mole ratio of the acid to base is 1.

Data obtained from the question include:

Ma = 0.25M

Va = 26.4mL

Mb =?

Vb = 30mL

Ma x Va = Mb x Vb

Mb = (Ma x Va) / Vb

Mb = ( 0.25x26.4 ) / 30

Mb = 0.22M

Therefore, the molarity of CsOH is 0.22M

answer is: naturally occurring solid, inorganic compound or element is mineral.

minerals usually have crystalline form, that means than crystal constituents (atoms, molecules or ions) are arranged in a highly ordered microscopic structure, forming a crystal lattice that extends in all directions.

for example magnetite is a mineral of iron oxide (fe₂o₃).

calcite is a carbonate mineral and the most stable polymorph of calcium carbonate (caco₃).

dolomite is an   carbonate mineral composed of calcium magnesium carbonate (camg(co₃)₂).
