How many moles are found in a 100.0 g sample of CuF2?
2 answers:
<span>The molar mass is calculated by the sum of the mass numbers of the atoms that form the molecule. For example: CuF2
</span>Cu: 1*63,54u = 63,54u
F: 2*19u = 38u
Thus, the molar mass of CuF2 is: 63,54+38= 101,54 g/ mol.
<span>And the number of mol is calculated by the mass divided by the molar mass or it can be solving through the rule of 3. For example:
</span>100 g de CuF2
101,54 g → 1 mol
100 g → x
101,54x = 100
x = 100/101,54
x = 0,98483... →

Answer:
The structures are shown in the figure.
Explanation:
The primary hydrogens are those which are attached to primary carbon.
Primary carbons are the carbons which are attached to only one carbon.
Primary carbons is bonded to three hydrogens.
In order to draw such structure we will draw structures which will have carbon with three hydrogens or no hydrogens (quaternary)
The structures are shown in the figure with clear marking.
