well when there is more kinetic energy in a solution the higher its temperature is going to be so the more the molecules are able to be help together, the lower the temperature the more difficult it would be to break the molecule apart in order to bond with it.
Answer:
<h2>The answer is 9 g/cm³</h2>
Explanation:
The density of a substance can be found by using the formula
From the question
mass = 216 g
volume = 24 cm³
The density is
We have the final answer as
<h3>9 g/cm³</h3>
Hope this helps you
Answer:
the volume of CHCI3 = 7.87 ml
the volume of CHBr3 = 12.13 ml
Explanation:
From the given information:
We all know that 1 g/cm^3 = 1 g/ml
The density of boron = 2.34 g/ml
The Volume of the liquid mixture = 20 ml
Recall that:
Density = mass/volume
Mass = Density × Volume
Mass = 2.34 g/ml × 20 ml
Mass = 46.8 g
Suppose the volume of CHCI3 be Y and the Volume of CHBr3 be 20 - Y
Then :
Y (1.492) + 20-Y(2.890) = 46.8
1.492Y + 57.8 - 2.890Y = 46.8
- 1.398 Y = -11
Y = -11/ - 1.398
Y = 7.87 ml
Therefore, the volume of CHCI3 7.87 ml
the volume of CHBr3 = 20 - Y
= 20 - 7.87
= 12.13 ml
