Question

How many moles of chlorine gas are needed to make 0.6 moles of sodium chloride given the reaction: `2Na + Cl_2 -> 2NaCl`?

Answer 1

0.3 moles of chlorine gas gives 0.6 moles of sodium chloride

Explanation:

as, 1 mole of Cl`rarr`2 moles of NaCl
so, 1 mole of NaCl`rarr 1/2`moles of Cl
now, 0.6 mole NaCl`rarr1/2*0.6` moles of Cl
i.e. =`1/2*0.6=0.5*0.6`
=`0.3` moles of Cl
