1) We apply the ideal gas equation:
PV = nRT
n = (21300 x 3/1000) / (8.314 x 323)
n = 0.024
Your answer is correct.
2) Total pressure = Partial pressure of Hydrogen + Partial pressure of water
134.7 = 122.4 + Pw
Pw = 12.3 kPa
Your answer is correct
3) The molar fraction, volume fraction and pressure fraction of gasses are the same thing.
Thus, percentage pressure of Oxygen = 10%
Pressure of Oxygen = 2.04 x 10⁴ x 0.1
= 2.04 x 10³ kPa
Your answer is correct
Well done!
They can be differnt shape or one must weight more then the other one
Answer:
2,7,4,6
Explanation:
atoms at the left side should be equal to that of right for an equation to be balanced. so the answer is the final one
Answer:
0.2788 M
1.674 %(m/V)
Explanation:
Step 1: Write the balanced equation
NaOH + CH₃COOH → CH₃COONa + H₂O
Step 2: Calculate the reacting moles of NaOH

Step 3: Calculate the reacting moles of CH₃COOH
The molar ratio of NaOH to CH₃COOH is 1:1.

Step 4: Calculate the molarity of the acetic acid solution

Step 5: Calculate the mass of acetic acid
The molar mass of acetic acid is 60.05 g/mol.

Step 6: Calculate the percentage of acetic acid in the solution
