The density of a 10.127 molal ethanol/water solution (ethanol is C2H6O, FW 46.07) is 0.9392 g/mL at 20 ˚C. Calculate the mass percent of ethanol in the solution at 20 ˚C.

Elements would be the right answer

Using dilution equationm1v1 =m2v2 ; where m1 and m1 are the intiial and final concentration, and v1 and v2 are the initial and final volume.5  × 5 m = 8 l  × m2m2 = 25/8 = 3.125 mtherefore; the resulting molarity is 3.125 m

Looking up graphs on google, you can see thaty = force(n)x = time(s)

This answer is homologous series good luck
