The answer & explanation for this question is given in the attachment below.
Answer:
None of them
Explanation:
The number of moles in 75ml is 0.01875moles while in 25ml is 0.004375 and in 129 ml is 0.018705.
REMEMBER: Molarity is the number of moles per litre so in order to get the number of moles you multiply the molarity of the substance by the quantity of the substance in litres.
Answer:
The answer to your question is Volume = 0.7 l
Explanation:
Data
Volume 1 = V1 = 0.746 l
Pressure 1 = P1 = 94.6 kPa
Volume 2 = V2 = ?
Pressure 2 = 101.33 kPa
Process
To solve this process use Boyle's law.
P1V1 = P2V2
-Solve for V2
V2 = P1V1/P2
-Substitution
V2 = (94.6 x 0.746) / 101.33
-Simplification
V2 = 70.57 / 101.33
-Result
V2 = 0.696 l ≈ 0.7 l
<span>A substance dissolves in water by breaking up into smaller pieces. these pieces of the same substance spread throughout the water. this process is known as d</span>iffusion.
In short, your answer would be : Diffusion.
