6 0

its me again this is how you find the answer. note: i dont have the periodic table to see the exact atomic mass to find the molar mass however this is the answer:

so the actual formula is Mg(OH) with a 2 as a subscript because there are 2 Mg. so with Mg(OH)2 the Molar mass is 58.32g/mol. 58.32 g/mol x 7.1x1024 = 4.1x1026g

What is the energy of a photon of green light whose frequency is 6.85 X 1014/seC?
Anvisha [2.4K]

Frequency of photon = is 6.85 X 10¹⁴ sec⁻¹

Energy of photon , E = hv

where h is Planck's constant, v is the frequency of photon

E = 6.63 × 10⁻³⁴ J.s x 6.85 X 10¹⁴ s⁻¹

E = 4.54 x 10⁻¹⁹ J

Therefore, the energy of a photon of green light is 4.54 x 10⁻¹⁹ J.

Calculate the energy of a photon of this light wave in joules. [Show all calculations, including the equation and substitution w
Ket [755]

The energy of the photon from the calculation performed is 3.5 * 10^-16 J.

<h3>What is a photon?</h3>

A photon is a packet of light. It was derived from the theory of Albert Einstein. The energy of a photon is obtained from; E = hc/λ

  • h= Plank's constant
  • c = speed of light
  • λ = wavelength

Now we have that;

E = 6.6 * 10^-34 * 3 * 10^8/562 * 10^-9

E = 3.5 * 10^-16 J

Missing parts:

Calculate the energy, in joules, of a photon of green light having a wavelength of 562nm?

How is the mass of carbon related to the mole?
Anuta_ua [19.1K]

Answer:

Simply put, you can go from moles to grams and vice versa by using the mass of 1 mole of that substance, i.e its molar mass. For example, the molar mass of carbon is 12.011 g/mol. This means that 1 mole of carbon, or 6.022⋅1023 atoms of carbon, weigh 12.011 g.
