Answer:
bond angles of 120 degrees.
The two liquids are different and so the melting points are different only because one represents an intermediate stage. It was a melting-point suppression effect, just like salt and ice, but it was much larger than anyone on the team had thought possible.
Hydrogen, hydrogen ion (H+) is associated with acids
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.
Answer: The new volume of cake is 1.31 mL.
Explanation:
Given:
= 0.20 mL, 
= ?, 
Formula used to calculate new volume is as follows.

Substitute the values into above formula as follows.

Thus, we can conclude that the new volume of cake is 1.31 mL.
