What is the percent composition by mass of aspartame #C_14H_18N_2O_5#?

Answer 1

Wyatt Adkins

I will solve for percentage composition of #N# in the compound.

Molecular mass of aspartame: #=# #(14xx12.011+18xx1.00794+2xx14.011+5xx15.999)*g*mol^-1#

#=# #294.31# #g*mol^-1#.

However, we are interested in the sample's percentage nitrogen composition:

#(2xx14.011*g*mol^-1)/(294.31*g*mol^-1)# #xx# #100%# #=# #??%#

Keep in mind that the total of each elemental percentage needs to be 100%. Why?

When evaluating a one-sided limit, you need to be careful when a quantity is approaching zero since its sign is different depending on which way it is approaching zero from. Let us look at some examples.
