In the titration of 50. 0 mL of 0. 400 M HCOOH with 0. 150 M LiOH, how many mL of LiOH are required to reach the equivalence poi
mart [117]

The volume of the 0.15 M LiOH solution required to react with 50 mL of 0.4 M HCOOH to the equivalence point is 133.3 mL

<h3>Balanced equation </h3>

HCOOH + LiOH —> HCOOLi + H₂O

From the balanced equation above,

The mole ratio of the acid, HCOOH (nA) = 1

The mole ratio of the base, LiOH (nB) = 1

<h3>How to determine the volume of LiOH </h3>
  • Molarity of acid, HCOOH (Ma) = 0.4 M
  • Volume of acid, HCOOH (Va) = 50 mL
  • Molarity of base, LiOH (Mb) = 0.15 M
  • Volume of base, LiOH (Vb) =?

MaVa / MbVb = nA / nB

(0.4 × 50) / (0.15 × Vb) = 1

20 / (0.15 × Vb) = 1

Cross multiply

0.15 × Vb = 20

Divide both side by 0.15

Vb = 20 / 0.15

Vb = 133.3 mL

Thus, the volume of the LiOH solution needed is 133.3 mL

a material has a density of 8.9 g/cm^3. You have six cubic centimeters of the substance. What is the material's mass in grams?
Svet_ta [14]
If the formula for density=m/v, you can manipulate this formula to the the mass. After manipulation, you get the equation for mass to be: m=density * volume. With density and volume given, we can find the mass.

mass= (8.9) * 6 = 53.4grams

What is the percent by mass of 110.6 g of potassium fluoride (NaF) dissolved in 1500.0 g of
sveta [45]

The percent by mass of 110.6 g of potassium fluoride (NaF) dissolved in 1500.0 g of water is 0.073733 %.

<h3>What is the mass percentage?</h3>

The mass percent of a solution is defined as the ratio of the mass of solute that is present in a solution, relative to the mass of the solution, as a whole.

\rm\;Mass \;percentage =\frac{\;Mass \;of \;solute}{\;Mass \;of \;solution}

Calculate the mass percent of potassium fluoride, using the formula:

\rm\;Mass \;percentage =\frac{\;Potassium \;fluoride}{\;Mass \;of \;Water}

\rm\;Mass \;percentage =\frac{110.6}{1500.0}

Mass percentage = 0.073733 %

Hence,  the percent by mass of 110.6 g of potassium fluoride (NaF) dissolved in 1500.0 g of water is 0.073733 %.
