If you have 16 g of manganese (II) nitrate tetrahydrate, how much water is required to prepare 0.16 M solution from this amount

nirvana33 [79]

<u>Answer:</u> The volume of water required is 398 mL

<u>Explanation:</u>

To calculate the molarity of solution, we use the equation:

$\text{Molarity of the solution}=\frac{\text{Mass of solute}\times 1000}{\text{Molar mass of solute}\times \text{Volume of solution (in mL)}}$

We are given:

Mass of solute (manganese (II) nitrate tetrahydrate) = 16 g

Molar mass of manganese (II) nitrate tetrahydrate = 251 g/mol

Molarity of solution = 0.16 M

Putting values in above equation, we get:

$0.16M=\frac{16g\times 1000}{251g/mol\times \text{Volume of solution}}\\\\\text{Volume of solution}=398mL$

Hence, the volume of water required is 398 mL

The formula vw=f⋅λ describes the relationship between the speed of a wave (vw), and its frequency (f) and wavelength (λ). For ex

GrogVix [38]

If the wavelength of the wave is increased to 10 m, the frequency of the wave will be 60 Hz

<h3>Data obtained from the question </h3>

Wavelength (λ) = 10 m
Velocity (v) = 600 m/s

Frequency (f) =?

<h3>How to determine the frequency of the wave </h3>

The frequency, wavelength and velocity of a wave are related according to the following equation:

Frequency (f) = velocity (v) / wavelength (λ)

f = v / λ

With the above formula, we can obtain the frequency of the wave as follow

f = v / λ

f = 600 / 10

f = 60 Hz
