Answer: The final concentration is 0.16 M.
Explanation:
According to the dilution law:
where,
= molarity of stock solution = 1.60 M
= volume of stock solution = 54.0 ml
= molarity of diluted solution = ?
= volume of diluted solution = 218 ml
Putting these values:
Now 109 ml of this diluted solution is further diluted by adding 161 mL of water.
Again applying dilution law:
Thus the final concentration is 0.16 M
This substance is certainly not gas since gas particles have large spaces between them. This substance is certainly not solid as well since solid particles are closely packed together with very close proximity. This substance is therefore liquid since particles are still close but can move around in a disordered arrangement.

Hey mate
SORTING METHOD can easily be used to separate a mixture of steel ball bearing and marbles. This separation method is suitable because the two substances that are mixed together have big sizes, so it is easy to separate the two by hand picking the particles. Sorting method is usually used as a separation technique when the size of the mixture is big and the mixed substances are in the same state.
