Sagot :
The number of formula units in the 17.6 g copper (II) chloride sample is [tex]7.88\;\times\;10^2^2[/tex]option A is correct.
The formula unit is given as the molecule of the compound with constituent atoms and bonds.
Computation for the number of formula units
The number of formula units in a mole of sample is equal to the Avogadro number. The Avogadro number is a constant with the value of [tex]6.023\;\times\;10^2^3[/tex].
Thus, the number of formula units in copper (II) chloride are:
[tex]\rm 1\;mol=6.023\;\times\;10^2^3\;formula\;unit\\134.45\;g/mol=6.023\;\times\;10^2^3\;formula\;unit[/tex]
The given mass of copper chloride is 17.6 g. The number of formula units is given as:
[tex]\rm 134.45\;g=6.023\;\times\;10^2^3\;units\\\\17.6\;g=\dfrac{6.023\;\times\;10^2^3}{134.45}\;\times\;17.6\;units\\\\ 17.6\;g=7.88\;\times\;10^2^2\;units[/tex]
The number of formula units in the 17.6 g copper (II) chloride sample is [tex]7.88\;\times\;10^2^2[/tex] units.
Thus, option A is correct.
