The concentration after dilution is 1.4%.
We are aware that concentration and volume are related to each other by the formula -
= 
, where we have initial concentration and volume on Left Hand Side and final concentration and volume on Right Hand Side.
Keep the values to calculate final concentration.
= (53.5 × 5.4)/205.0
Performing multiplication on Right and Side
= 288.9/205.0
Performing division on Right Hand Side
= 1.4%
Hence, the final concentration is 1.4%.

The complete question is -
A 53.5 mL sample of an 5.4 % (m/v) KBr solution is diluted with water so that the final volume is 205.0 mL.
Calculate the final concentration and express your answer to two significant figures and include the appropriate units.
The movement of water on and above the earth's surface is called the hydrologic cycle, or the water cycle. Hope this helps!
Answer:
a. Expansion: the spatial dilation of a material that occurs upon changes in its composition. (an increase in number or amount to become larger in size.)
E.g- in a thermometer, when it gets hotter, the liquid inside them expands and rises up the tube.
b. Sublimation: the process in which a solid changes directly into a liquid.
E.g- dry ice, solid iodine and ammonium salts.
when the above solids are heated, only particles which are found on the surface of the solid have enough energy to break all forces of attraction and form a gas.
c. Contraction: it is the opposite of expansion. when a liquid is cooled the particles slow down and contract.
E.g- when a thermometer is taken out of your mouth, it contracts and the liquid inside falls back to the bottom.
f. Random Motion: motion in which the particle moves in a zig-zag manner and not in a straight line. The kinetic particle theory states that matter is made up of particles which are in constant <em>random motion,</em>
Explanation:
Answer:C. Hydrogen Bonds with themselves and entropy decreases.
Explanation:Limonene is a chiral aliphatic Hydrocarbon liquid that is relatively stable as MONOTERPENE which cracks at high temperature to produce ISOPRENE. D-limonene is produced from CITRUS FRUIT through CENTRIFUGAL SEPARATION AND STEAM DISTILLATION. The most widely used conversion of limonene is to CARVONE.
The water molecules around LIMONENE forms Hydrogen Bonds with themselves and entropy of the reaction decreases,the name Limonene was obtained from the PEEL OF LEMON.
