What is the empirical formula of something that is 40% sodium and 60% chlorine

We let the empirical formula for the compound compost of sodium and chlorine as NaxCly. The molar mass of the empirical equation is,
                                    23x + 35y
 The percentages,
                         Na:       0.40 = 23x/ (23x + 35y)
                         Cl:        0.60 = 35y/ (23x + 35y)
The values of x and y from the equation are,
                                             x = 1 and y = 1
Thus, the answer is that the empirical formula is NaCl. 

Answer:

it was spontaneous.

explanation:

" is the name given to a speech, delivered extemporaneously, by sojourner truth, (1797–1883), born into slavery in new york state.sojourner truth' delivered her famous speech "ain't i a woman?
