How many moles are in 88.1 of magnesium

1 answer:

7 0

For this you need the atomic mass of Mg. Take the number of moles and multiply it by the atomic mass. Divide by one mole for units to cancel.

88.1 moles Mg × 24.3 grams = 2140.83 moles Mg

It is a radio wave

Explanation:

The energy of an electromagnetic waves is related to its frequency by the equation:

$E=hf$

where

h is the Planck constant

f is the frequency of the wave

We notice that the energy of an electromagnetic wave is proportional to its frequency. This means that waves with higher frequencies, such as gamma rays, x-rays, are more energetic, while waves with lower frequencies, such as microwave and radio waves, are the less energetic.

In this case, we want to find the frequency of a wave with energy

E = 0.000001 eV

Converting into Joules,

$E=1\cdot 10^{-6} eV \cdot 1.6\cdot 10^{-19} J/eV=1.6\cdot 10^{-25} J$
