The mass of a pot is 300g and contains 90% aluminum. Find the number of moles of aluminum in the pot. P.A. (Al = 27)
The mass of aluminum present in the pot is:
Hence, in the given pot 270g Al is present.
The gram atomic mass of Al -27 g/mol
Given the mass of Al is 270 g
Substitute these values in the above formula:
Answer is 10.0 mol of Al is present.
Answer:
76.875 cm3
<h2>Explanation:</h2>Since: Density =
Then: Volume =
The mass of the box = 246g
and the density = 3.2 g/cm3
Then: The volume =
= 76.875 cm3
