Answer:
3 moles of
is needed for
to be fully consumed.
Explanation:
For the balanced equation:
⇒ 
First, find the moles of Na corresponding to the 69g used the general definition of mol:

We observe that the equation is balanced and the stoichiometric ratio between them is 1: 1.
According to this, one mole of Na will react with one mole of Cl.
3 moles of
is needed for
to be fully consumed.

The value that describe temperature and pressure (STP) is 273.15 K and 101.3 KPa (answer D)
<em><u>Explanation</u></em>
International union of pure and applied chemistry ( IUPAC) established standard temperature and pressure (STP) as below,
temperature 0°c which is the same as 273.15 K
Pressure = 1 atm which is the same = 101.325 KPa or 1.01325 bar
