Answer:
2.23 atoms
Explanation:
In this question, we first need to change the mass of Nitrogen to moles by using the formula;
mole = mass ÷ molar mass
Molar mass of Nitrogen = 14g/mol
Mass = 5.2x10^-23 grams
mole = 5.2x10^-23 ÷ 14
mole = 0.371 × 10^-23
mole = 3.71 × 10^-24 mol
Number of atoms in Nitrogen atom = 3.71 × 10^-24 mol × 6.02 × 10^23 atoms (avagadro constant)
= 22.3342 × 10^(-24+23)
= 22.33 × 10-¹
= 2.233 × 10°
= 2.23 atoms
I found this that should help.
“Heat of Vaporization” it takes energy to evaporate sweat off of your skin and that energy is heat. As your excess body heat is used to convert beads of sweat and vapor you start to cool down.
Answer:
The Answer is Telophase
Explanation:
It is helpful to remember PMAT. P stands for Prophase which is when the DNA is replicated. M stands for Metaphase which is when the chromosomes line up in the center of the cell. A stands for Anaphase which is when the spindle fibers attach to the chromatids and pulls one to either side of the cell. T stands for Telophase which is when the cell division starts to create the two daughter cells.
