A student delivered 17.06 mL (V1) of 7.16 % stock solution (M1) using a graduated pipette into a 50.00 mL (V2) volumetric flask.

Distilled water was added to the flask to the graduation mark and mixed well.
Using the dilution equation (provided below), calculate the concentration of the diluted solution.

(M1)(V1) = (M2)(V2)

The concentration of the diluted solution will be 2.44%.

<h3>Dilution problem</h3>

From the equation of dilution:

(M1)(V1) = (M2)(V2).

where M1 = concentration before dilution, M2 = concentration after dilution, V1 = volume before dilution, and V2 = volume after dilution.

In this case:

V1 = 17.06 mL

V2 = 50.00 mL

M1 = 7.16%

M2 = ?

M2 = (M1)(V1)/(V2)

        = 7.16 x 17.06/50

               = 2.44%

Thus, the concentration of the diluted solution is 2.44%.

How many moles and molecules are there in 250g of hydrogen nitrate, HNO3
Viefleur [7K]

Answer:

Number of molecules = 23.9  × 10²³ molecules

Number of moles = 3.97 mol

Explanation:

Mass of HNO₃ = 250 g

Number of moles = ?

Number of molecules = ?

Solution:

Number of moles = mass / molar mass

Number of moles = 250 g/63 g/mol

Number of moles = 3.97 mol

Number of molecules:

The given problem will solve by using Avogadro number.

It is the number of atoms , ions and molecules in one gram atom of element, one gram molecules of compound and one gram ions of a substance.

The number 6.022 × 10²³ is called Avogadro number.

For example,

18 g of water = 1 mole = 6.022 × 10²³ molecules of water

1.008 g of hydrogen = 1 mole = 6.022 × 10²³ atoms of hydrogen

For 250 g of HNO₃:

250 g/ 63 g/mol = 3.97 mole

3.97 × 6.022 × 10²³ molecules = 23.9  × 10²³ molecules
