Spontaneous processes are processes that occurs freely they do not need any other external factors to be supplied for them to proceed while non-spontaneous ones requires input of energy for it to happen. Example of a spontaneous process is the decay of a diamond to graphite while the reverse of this is a non spontaneous process since heat and pressure are to be supplied for graphite to turn into diamond.

Determine the volume (in ml) of a 3.57 M solution of Zi Bry that contains 0.884 moles of ZnBr2
frosja888 [35]

Answer:

The  volume (in ml) of a 3.57 M solution of ZnBr_2 that contains 0.884 moles of  ZnBr_2 is 247.61g mL

Explanation:

According to the definition of Molarity

which sates

"The amount of moles of a substance present in one litre of the solution is called as Molarity."

3.57M ZnBr_2 solution implies that 1000 mL of the solution conatins 3.57Moles of ZnBr_2

Hence , 3.57 moles of ZnBr_2 is present in the 1000 ml of solution

Now,

In 1 mole of ZnBr_2 is  present in the =\frac{1000}{3.57}ml of solution

Similarily ,

In 0.884  moles ofZnBr_2 is  present in the \frac{1000\times 0.884}{3.57} of solution= 247.61g mL
