Answer:

We take the quotient...#n_"NaOH"="mass of sodium hydroxide"/"molar mass of sodium hydroxide"#

Explanation:

And so...

#n_"NaOH"=(0.450*g)/(40.00*g*mol^-1)=0.0113*mol#

Note the dimensional consistency of the answer. The #g# cancel...and we get an answer in #(cancelg)/(cancelg*mol^-1)=1/(mol^-1)=1/(1/(mol))=mol#...as required...
