Answer:- Solubility of the gas at 759 torr is 0.00753 g/L.
Solution:- From given data, 0.00327 g of gas is soluble in 0.376 L of water at 876 torr.
Solubility of gas at 876 torr pressure is = 0.00327g/0.376L = 0.00869 g/L
Solubility of gases is directly proportional to the pressure. It means, grater is the pressure, more is the solubility of gases.
So, 0.00869/876 = X/759
Where, X is the solubility of the gas at 759 torr.
X = 0.00869(759)/876
X = 0.00753 g/L
Answer:
<h3>The answer is 223.0 cm³</h3>
Explanation:
To find the volume when the pressure is at 202.6 kPa we use Boyle's law which is

where
P1 is the initial pressure
P2 is the final pressure
V1 is the initial volume
V2 is the final volume
Since we are finding the final volume

From the question
P1 = 99.3 kPa = 99300 Pa
V1 = 455 cm³
P2 = 202.6 kPa = 202600
So we have

We have the final answer as
<h3>223.0 cm³</h3>
Hope this helps you
The answer is C: A surfer rides back to the beach on his surf board.
All the others are examples of people doing stuff to the water, C is an example of the water moving something, in this case the water is moving a surfer and his surf board.
<u>Answer:</u> The percentage abundance of
isotope is 69 %.
<u>Explanation:</u>
Average atomic mass of an element is defined as the sum of masses of each isotope each multiplied by their natural fractional abundance.
Formula used to calculate average atomic mass follows:
.....(1)
We are given:
Let the fractional abundance of
isotope be 'x'
- <u>For
isotope:</u>
Mass of
isotope = 62.93 amu
Fractional abundance of
isotope = x
- <u>For
isotope:</u>
Mass of
isotope = 64.93 amu
Fractional abundance of
isotope = (1-x)
- Average atomic mass of copper = 63.55 amu
Putting values in above equation, we get:
![63.55=[(62.93\times x)+(64.93\times (1-x))]\\\\x=0.69](https://tex.z-dn.net/?f=63.55%3D%5B%2862.93%5Ctimes%20x%29%2B%2864.93%5Ctimes%20%281-x%29%29%5D%5C%5C%5C%5Cx%3D0.69)
Converting this fractional abundance into percentage abundance by multiplying it by 100, we get:

Hence, the percentage abundance of
isotope is 69 %.
