In which location would you expect to find the greatest species diversity?!
7nadin3 [17]
The correct answer is D : United States

All of the other countries on the list have great species diversity, especially Cosa Rica due to it's closeness to the equator and therefore its tropical climate perfectly suitable for wildlife thrive.
But, the United States' territory covers the areas with the mild climate, forests, deserts, canyons and species-rich coastal regions as well as the Hawaii islands with unique species diversity and the Alaskan area with the arctic habitat.

Debora [2.8K]

Answer:

12.7 mol

Explanation:

<em>A chemist measures the amount of fluorine gas produced during an experiment. He finds that 482. g of fluorine gas is produced. Calculate the number of moles of fluorine gas produced.</em>

Step 1: Given data

Mass of fluorine (m): 482. g

Step 2: Determine the molar mass (M) of fluorine

Fluorine is a diatomic molecule of chemical formula F₂. Its molar mass is:

mF₂ = 2 × mF = 2 × 19.00 g/mol = 38.00 g/mol

Step 3: Determine the number of moles (n) corresponding to 482. g of fluorine

We will use the following expression,.

n = m/M

n = 482. g/(38.00 g/mol)

n = 12.7 mol

How many atoms of N are in 137.0 grams of N2O3?
olasank [31]

Answer: The number of N atoms in 137.0 g of N2O3 21.67 x 10∧23 atoms.

Explanation:

  • We must obtain the number of moles of the compound: (n = mass/molar mass), mass = 137.0 g and molar mass of N2O3 = 76.01 g/mol.
  • n = (137.0 g)/ (76.01 g/mol) = 1.80 mol.
  • It is necessary to determine the number of molecules of this sample.
  • Every mole contains Avagadro's number (6.02 x 10^23) of molecules.
  • The number of molecules = (6.02 x 10^23)(1.80) = 10.84 x 10∧23 molecules.
  • Every molecule of N2O3 contain 2 atoms of N.
  • The number of N atoms in 137.0 g of N2O3 = (10.84 x 10∧23 molecule) (2 atoms) = 21.67 x 10∧23 atoms.
