Z=0.43y+12=28=0.43y+12=28-12=0.43y=16=0.43y,then u divide 0.43y by itself and by 16,you will get y=37.209
Answer:
Albert Einstein proposed that a beam of light is not a wave propagating through space, but a collection of discrete wave packets—photons.
Explanation:
So the right answer is the first one.
One electron has a mass of 9.10938291 x 10^−<span>31 kg. One mole of electrons contains 6.022x10^23 electrons where half of a mole is has 3.011x10^23 electrons. Therefore, the mass of half a mole of electrons would be 2.74x10^-7. Hope this answers the question. Have a nice day.</span>
