What is the frequency, in hertz, of an electromagnetic wave with a wavelength of 625 nm?
Reika [66]

Answer:- Frequency is 4.80*10^1^4Hz .

Solution:- The wavelength of electromagnetic radiation is given as 625 nm and we are asked to calculate the frequency. Frequency is inversely proportional to the wavelength and the formula used to calculate frequency when wavelength is given is:

\nu =\frac{c}{\lambda }

where, \nu is frequency, c is speed of light and \lambda is the wavelength.

Value of speed of light is \frac{3.0*10^8m}{s} . We need to convert the given wavelength from nm to m.

1nm=10^-^9m

So, 625nm(\frac{10^-^9m}{1nm})

= 6.25*10^-^7m

Let's plug in the values in the formula and calculate the frequency:

\nu =\frac{3.0*10^8m.s^-^1}{6.25*10^-^7m}

= 4.80*10^1^4s^-^1 or Hz.

So, the frequency of the electromagnetic wave is 4.80*10^1^4Hz .

The molar mass of an element is the mass of one
allochka39001 [22]

Answer:

  • <em>The molar mass of an element is the mass of </em><u>one mole of atoms of the element.</u>

Explanation:

<em>The molar mass of an element </em>is its atomic mass, i.e.  the mass in grams of one mole of atoms of the element.

Remember 1 mol is approximately 6.022 × 10²³.

So, 1 mol of atoms is 6.022 × 10²³ atoms.

The molar mass is an average: it is the weighted average mass of the natural isotopes of the element, taking into account their relative abundance.

For example, the molar mass or atomic mass of carbon is 12,0107 g/mol, instead of 12.0000, becasue carbon exists in several forms (isotopes), and so the weighted average is not a whole number.
