#"2.5 mol Cl"_2"# will react with #"5 mol Na"#.

Explanation:

Balanced Equation

#"2Na(s)" + "Cl"_2("g")##rarr##"2NaCl(s)"#

Multiply the given moles of #"Na"# times the mole ratio #(1"mol Cl"_2)/(2"mol Na")# from the balanced equation.

#5cancel"mol Na"xx(1"mol Cl"_2)/(2cancel"mol Na")="2.5 mol Cl"_2"#
