Question

Sodium and chlorine react to form sodium chloride. If there are 1.4 moles of sodium used, how many moles of chlorine were required?

Answer 1

0.7 moles of Chlorine gas is required.

Step-by-step explanation:

The reaction is balanced as follows:

2Na +
`Cl_(2)` ------> 2NaCl

According to stoichiometry,

2 mole Sodium reacts with 1 mole Chlorine gas

∴1 mole Sodium reacts with 1/2 moles of Chlorine gas

∴1.4 mole sodium reacts with 1.4/2 moles of Chlorine gas

= 0.7 moles of Chlorine gas

So, 0.7 moles of Chlorine gas is required.
