If 250.0 mL of a 0.96 M solution of acetic acid (C 2H 4O 2) are diluted to 800.0 mL, what will be the approximate molarity of the final solution?

0.30M HOAc

Explanation:

Given 250.0ml (0.96M HOAc) => 800ml(??M HOAc)

Use the dilution equation...

(Molarity x Volume)concentrated soln = (Molarity x Volume)dilute soln

(0.96M)(250.0ml) = (Molarity diluted soln)(800ml)

Molarity diluted soln = (0.96M)(250.0ml)/(800ml) = 0.30M HOAc

c. because step up transformer steps up the input voltage i.e increases the input voltage  

the number of turns are greater on the secondary side of step up transformer  

transformer does not handle dc current

i believe that it is a exoplanet
