In the gaseous state, chlorine exists as a diatomic molecule Cl2 (Molar mass = 70.9 g/mol). Calculate the number of moles of chl
Annette [7]

Answer:

3.67 mol Cl

Explanation:

We need to convert g of Cl 2 to moles of Cl. First we divide 130 gCl2  by the molar mass (70.90 gCl2/mol) to find out how many moles of Cl2 do we have.

130 gCl2 x \frac{1 mol Cl2 }{70.90 gCl2} = 1.83 mol Cl2

Then we need to convert 1.83 mol de Cl2 to moles of Cl. We have 2 moles of Cl in every Cl2 molecule so we just need to multiply by 2.

1.83 molCl2 x \frac{2 molCl}{1 molCl2} = 3.67 molCl

What is the energy of an electromagnetic wave with a frequency of 8 x 10^12
omeli [17]

Answer:

Energy, E=5.3\times 10^{-21}\ J

Explanation:

It is required to find the energy of an electromagnetic wave with a frequency of 8\times 10^{12}\ Hz. The energy of a wave in terms of its frequency is given by :

E=h\nu

\nu = frequency of em wave

E=6.63\times 10^{-34}\times 8\times 10^{12}\\\\E=5.3\times 10^{-21}\ J

So, the energy of an electromagnetic wave is 5.3\times 10^{-21}\ J
