A 0.410 g sample of a monoprotic acid is dissolved in water and titrated with 0.190 M KOH . What is the molar mass of the acid i
Juliette [100K]

Answer: Molar mass of the acid is 89.91 g/mol.

Explanation:

The given data is as follows.

    Weight of monoprotic acid = 0.410 g

    Molarity of KOH = 0.190 M

    Volume of KOH used = 24 ml = 0.024 L    (as 1 ml = 0.001 L)

First, we will calculate the number of moles of KOH as follows.

    No. of moles = Molarity × Volume

                        = 0.190 \times 0.024  

                        = 0.00456 mol

So, using KOH the given monoprotic acid is neutralized in 1:1 ratio. Therefore,

  moles of monoprotic acid = moles of KOH

                                          = 0.00456 mol

Hence, we will calculate the molar mass as follows.

     Molar mass = \frac{\text{mass of monoprotic acid}}{\text{no. of moles of acid}}

                         = \frac{0.410 g}{0.00456 mol}

                         = 89.91 g/mol

Thus, we can conclude that molar mass of the acid is 89.91 g/mol.

I need help with this pls help
dusya [7]

Answer:

L X W

Explanation:

Area is the amount of space in a 2-dimensional figure. You do this by Length x width, which is the same as Base x width. Take a rectangle for instance. The length is 5 feet and the width is 7 feet. To find the area you do 5 by 7/ 5 x 7. 5 x 7 = 35. The area is 35 square feet/ 35 sq².

I will give brainliest!! How long is the pencil? Make sure to use the appropriate amount of significant figures.
8090 [49]

Answer: Option (c) is the correct answer.

Explanation:

The bottom of pencil is placed at the starting point of scale. Whereas the tip of pencil depicts the end point of its length.

The bottom of pencil is at 0 mm and tip of pencil is at 18.73 mm. The appropriate amount of significant figures is 18.73 mm.

Therefore, we can conclude that out of the given options, pencil is 18.73 mm long.
