Answer:
The number of molecules in a mole (known as Avogadro's constant) is defined such that the mass of one mole of a substance, expressed in grams, is equal to the mean molecular mass of the substance. The molecular mass of CO2 = 12+2x16 = 44, so the mass of a mole of CO2 is approximalty 44 grams
Explanation:
G(2)=2
For this, you can plug in 2 everywhere you see an n. So the equation will read:
g(2)=g(2-1)+2 -> g(2)=g(1)+2. Since we are given g(1)=0, we can plug in 0 where we see g(1). The equation is now. g(2)=0+2. So, g(2)=2.
<span>29 protons and 27 electrons.
Since the element is copper, that automatically means that you have 29 protons. Any other number would be an element other than copper. The 2+ indicates that the ion has a positive charge of 2. So it is missing 2 electrons. Since a neutral atom would have 29 electrons and you're missing 2, the number of electrons will be 29 - 2 = 27
So the answer is 29 protons and 27 electrons.</span>
