2Na+Cl2→2NaCl
How many grams of NaCl will be produced from 18.0 g of Na and 23.0g of Cl2?

37.44 grams of sodium chloride will be produced.

The mole concept of the compound is necessary for solving these types of problems.

Atomic weight of sodium = 23.

Atomic weight of chlorine = 35.5.

So, molecular weight of chlorine = 71.

So number of moles of sodium present =

=0.78

So,number of moles of chlorine present =

= 0.32

1 mole of chlorine reacts with 2 moles of sodium to form 2 moles of sodium chloride.

So, 0.32 moles of chlorine will react with 0.64 moles of sodium to form 0.64 moles of sodium chloride.

As sodium is present in excess, so chlorine is the limiting reagent.

Molecular weight of sodium chloride= = 58.5.

So, weight of sodium chloride produced = grams = 37.44 grams.

Increasing the temperature of a gas increases the pressure.
