Answer:
Number of moles = mass/molar mass
Explanation:
Given data:
mass of Al = 11 g
Moles = ?
Solution:
Formula:
Number of moles = mass/molar mass
Molar mass of aluminium is 27 g/mol
Now we will put the values in formula.
Number of moles = 11 g/ 27 g/mol
Number of moles = 0.41
The number of moles in 11 g Al are 0.41 mol.

Ans) 1.3 bison/mile
Soln:} See according to the question, Yellowstone National Park has an average of about 4500 bison living in it.
Area covered by Yellowstone park is 3472 miles.
So, to find the density of bisons living in Yellowstone Park we have to divide the no. of bisons by given area.
= 4500/3472
which is approximately 1.3 bisons per mile.
Therefore option a) is correct
