How would you find 8m of carbon chloride using 87.9g carbon chloride
vaieri [72.5K]

Answer:

Explanation:

I want to believe that your question is how to find an 8M carbon chloride solution using the given mass of the compound.

The problem clearly identifies with concentration of a substance. Molarity is one of the ways of expressing concentration. It is the amount of solute of a substance per volume of solution.

     Molarity  = \frac{number of moles of solute}{Volume of solution}

To find the right mix that will give us 8M carbon chloride solution, let's explore how to figure out the appropriate volume.

Clearly given is the mass of the compound, convert to number of moles.

  Number of moles  = \frac{mass}{molar mass}

            Molar mass of carbon chloride(CCl₄)  = 12 + 4(35.5)  = 154g/mol

Number of moles  = \frac{87.9}{154}   = 0.57moles

To find the volume;

            8    =    \frac{0.57}{v}

            volume = 0.071L or 71mL

Some instruments differentiate individual quanta of electromagnetic radiation based on their energies. assume such an instrument
bulgar [2K]

Answer:

5.68×10¯¹⁰ m

Explanation:

From the question given above, the following data were obtained:

Energy (E) = 3.50×10¯¹⁶ J

Wavelength (λ) =?

Energy (E) and wavelength (λ) are related according to the following formula:

E = hv/λ

Where

E => is the energy

h => is the Planck's constant

v => is the velocity of electromagnetic radiation

λ => is the wavelength of the radiation.

With the above formula, we can obtain the wavelength of the radiation as follow:

Energy (E) = 3.50×10¯¹⁶ J

Planck's constant (h) = 6.63×10¯³⁴ Js

Velocity (v) = 3×10⁸ m/s

Wavelength (λ) =?

E = hv/λ

3.50×10¯¹⁶ = 6.63×10¯³⁴ × 3×10⁸ / λ

3.50×10¯¹⁶ = 1.989×10¯²⁵/ λ

Cross multiply

3.50×10¯¹⁶ × λ = 1.989×10¯²⁵

Divide both side by 3.50×10¯¹⁶

λ = 1.989×10¯²⁵ / 3.50×10¯¹⁶

λ = 5.68×10¯¹⁰ m

Thus, the wavelength of the radiation is

5.68×10¯¹⁰ m
