Answer:
Although atoms are the smallest units that can be found in all matter, these atoms have a complex structure when experimentally analyzed. In order to understand almost all concepts in chemistry, it is essential to clearly understand the basic structure of an atom. Crystals are solid compounds made out of a number of atoms or molecules. There are particular arrangements in crystals. These arrangements are called crystal structures. Examining the crystal structure is very important in determine

Given:
Formula units of FeCl₃ = 8.65 x 10²³ formula units
Unknown:
Mass of the FeCl₃ = ?
Solution:
The formula unit is the same as the amount of subatomic particles in an atom.
1 mole of a substance = 6.02 x 10²³ formula units
For 8.65 x 10²³ formula units; the number of moles;
Number of moles = 
= 1.44moles
Now to find the mass of FeCl₃;
Mass of FeCl₃ = 1.44 x 162.2 = 233.1g

Answer:
The answer to your question is a) 2125 bicycles
c) No wheels, 630 frames, 130 handlebars.
Explanation:
Data
4250 wheels
2755 frames
2255 handlebars
- To manufacture a bicycle we need:
2 wheels x bicycle
1 frame
1 handlebar
- Divide the number of wheels
4250/ 2 = 2125 bicycles / wheels
2755 = frames
2255 = handlebars
As the number of pairs of wheels is lower than the number of frames and the number of handlebars we conclude that we can only manufacture 2125 bicycles.
b)
No wheels
Frames = 2755 - 2125 = 630
Handlebars = 2255 - 2125 = 130
The answer is c. 104 g because 152-64 equals 88 and 192-88 equals 105
