Answer:
<u></u>
Explanation:
<h2>Problem 1. </h2>
<u>a) Data:</u>
- n₁ = 0.126 mol
- V₁ = 2.74 L
- n₂ = 0.126mol + 0.124mol
- V₂ = ?
- Conditions: constant temperature and pressure
<u>b) Physical principles:</u>
The volume occupied by a gas, when the temperature and pressure remain unchanged, is proportional to the number of moles of gas.

<u>c) Solution:</u>
Solve for V₂ , substitute and compute:

<h2>Problem 2.</h2>
<u>a) Data:</u>
- n₁ = 0.547mol
- V₁ = 295 mL
- V₂ = ?
- n₂ = 0.547mol + 0.342 mol
- Conditions: constant temperature and pressure
<u>b) Physical principles:</u>
The same as above: the volume occupied by a gas, when the temperature and pressure remain unchanged, is proportional to the number of moles of gas.

<u>c) Solution:</u>
Solve for V₂ , substitute and compute:

1 mole of CO2 has 44g
so 1,5 moles would have 1,5*44=66g
the answer is 1) 66g
Each covalent H bond is nonpolar.
