Answer:
x=2.
Step-by-step explanation:
Hello there!
In this case, since we have a mole ratio of moles of Cl to moles of Cu as 2.39, it is possible to write the following:
Thus, since the two possible copper chlorides are CuCl and CuClâ‚‚, we can therefore infer that x=2 since it is close but not as close as it should to the whole number 2.
Best regards!
