Answer:
The volume of the dry gas at STP is = 0.4314 L
Explanation:
We are given:
Total vapor pressure = 740 mmHg
Also, considering Vapor pressure of water = 23.78 mmHg
Vapor pressure of gas = Total vapor pressure - Vapor pressure of water = (740 - 23.78) mmHg = 716.22 mmHg
We use the equation given by ideal gas which follows:
where,
P = pressure of the gas = 716.22 mmHg
V = Volume of the gas = 500 mL = 0.5 L ( 1 ml = 0.001 L )
T = Temperature of the gas =
R = Gas constant =
n = number of moles of gas = ?
Putting values in above equation, we get:
At STP, 1 mole of gas yields a volume of 22.4 L
So,
0.01926 mole of gas yields volume of
<u>Hence, the volume of the dry gas at STP is = 0.4314 L</u>

Explanation:
Answer:
6. Scientific inquiry - D
7. Hypothesis - E
8. Control group - G
9. Experimental group - A
10. Independent variable - B
11. Dependent variable - H
12. Scientific theory - C
13. Scientific law - F
Explanation:
6. Scientific inquiry - D
Scientific inquiry is the study of the explanation for the natural world phenomenon and it requires many scientific steps.
7. Hypothesis - E
A hypothesis is a possible explanation for a phenomenon or problem. It is tested in order to see if true or not.
8. Control group - G
The control group in a scientific experiment is a group of subjects did not get the treatment and left alone.
9. Experimental group - A
The experimental group is another hand group of subjects that gets treatment and shows the effect of the variable being tested.
10. Independent variable - B
Independent variables change or manipulated during an experiment and cause a response from the dependent variable.
11. Dependent variable - H
The dependent variable is a variable that is dependent on independent variables and changes in the independent variable.
12. Scientific theory - C
A well-tested explanation for experimental results with the scientific process.
13. Scientific law - F
This describes an observed pattern in nature
