Answer 1

`n_(Cl_2)=0.3molCl_2`

Step-by-step explanation:

Hello there!

In this case, according to the given chemical reaction whereas the sodium chloride is in a 2:1 mole ratio with chlorine, the required moles of the later are computed as shown below:

`n_(Cl_2)=0.6molNaCl*(1molCl_2)/(2molNaCl)`

So we cancel out the moles of NaCl to obtain:

`n_(Cl_2)=0.3molCl_2`

Best regards!
