Answer: Approximately ![0.48 \times 10^{-2} \ \text{ mole}](https://tex.z-dn.net/?f=0.48%20%20%5Ctimes%2010%5E%7B-2%7D%20%5C%20%5Ctext%7B%20mole%7D)
============================================================
Explanation:
There are roughly 6.02 * 10^23 atoms in one mole of any element. So we have 6.02 * 10^23 atoms in one mole of nitrogen.
We can then do the following conversion:
![\left(2.9 \times 10^{21} \ \text{ atoms of nitrogen} \right)\times \left(\frac{1 \ \text{ mole}}{6.02 \times 10^{23} \ \text{ atoms}}\right)\\\\\frac{2.9 \times 10^{21}}{6.02 \times 10^{23}} \ \text{ mole}\\\\\frac{2.9}{6.02} \times 10^{21-23} \ \text{ mole}\\\\0.48172757 \times 10^{-2} \ \text{ mole}\\\\0.48 \times 10^{-2} \ \text{ mole}\\\\](https://tex.z-dn.net/?f=%5Cleft%282.9%20%5Ctimes%2010%5E%7B21%7D%20%5C%20%5Ctext%7B%20atoms%20of%20nitrogen%7D%20%5Cright%29%5Ctimes%20%5Cleft%28%5Cfrac%7B1%20%5C%20%5Ctext%7B%20mole%7D%7D%7B6.02%20%5Ctimes%2010%5E%7B23%7D%20%5C%20%5Ctext%7B%20atoms%7D%7D%5Cright%29%5C%5C%5C%5C%5Cfrac%7B2.9%20%5Ctimes%2010%5E%7B21%7D%7D%7B6.02%20%5Ctimes%2010%5E%7B23%7D%7D%20%5C%20%5Ctext%7B%20mole%7D%5C%5C%5C%5C%5Cfrac%7B2.9%7D%7B6.02%7D%20%20%5Ctimes%2010%5E%7B21-23%7D%20%5C%20%5Ctext%7B%20mole%7D%5C%5C%5C%5C0.48172757%20%20%5Ctimes%2010%5E%7B-2%7D%20%5C%20%5Ctext%7B%20mole%7D%5C%5C%5C%5C0.48%20%20%5Ctimes%2010%5E%7B-2%7D%20%5C%20%5Ctext%7B%20mole%7D%5C%5C%5C%5C)
Answer:
Explanation:
The average atomic mass for any element will be closest to the average atomic mass of the __different______ isotopes.
To calculate the average atomic mass of any element, the mass spectrometry method helps to determine the proportion/percentage/fraction by which each of the isotopes of an element occurs in nature. The proportion is called the geonormal abundance or abundance. From this, the average atomic mass of an element from different isotopes can be calculated.
an invertebrate does not have a spine, while a vertebrate does.
I think the answer is: D) The reaction could spend more time in the reverse direction than in the forward direction.
Answer:
B. The region outside a nucleus where the electron is moving
Explanation:
The more the electron moves, the higher energy level it has, the slower the electron moves the lowwer energy level it has.
