Answer: The new pressure of the gas, assuming that no gas escaped during the experiment is 0.470 atm
Explanation:
Combined gas law is the combination of Boyle's law, Charles's law and Gay-Lussac's law.
The combined gas equation is,
where,
= initial pressure of gas = 0.732 atm
= final pressure of gas = ?
= initial volume of gas = 6.87 L
= final volume of gas = 9.22 L
= initial temperature of gas = 
= final temperature of gas = 
Now put all the given values in the above equation, we get:
Thus the new pressure of the gas, assuming that no gas escaped during the experiment is 0.470 atm
Answer:
1569 torr
Explanation:
Assuming ideal behaviour and constant temperature, we can solve this problem by using <em>Boyle's law</em>, which states:
Where in this case:
We <u>input the data given by the problem</u>:
- 202 mL * 505 torr = 65.0 mL * P₂
And <u>solve for P₂</u>:
Answer is: c. 1.204 × 10²⁴ atoms
of carbon.
n(C) = 2 mol; amount of substance of carbon.
Na = 6.02·10²³ 1/mol; Avogadro constant (the number of constituent particles, in this example atoms, that are contained in the amount of substance given by one mole).
N(C) = n(C) · Na.
N(C) = 2 mol · 6.02·10²³ 1/mol.
N(C) = 12.04·10²³ = 1.204·10²⁴; number of carbon atoms in a sample.
Answer:
E. None of the above statements are true.
