I’m sorry but I just wanted to say to my friends that you are not doing anything for you and you have a really nice night
A direct result of the Bay of Pigs invasion in 1961 was that "<span>Cold War tensions increased", mainly because this put into question the boundaries of both states. </span>

Explanation:</h3>
<u>Step 1: Define</u>
[Given] 0.456 g H₂O (water)
<u>Step 2: Identify Conversions</u>
[PT] Molar Mass of H - 1.01 g/mol
[PT] Molar Mass of O - 16.00 g/mol
Molar Mass of H₂O - 2(1.01) + 16.00 = 18.02 g/mol
<u>Step 3: Convert</u>

0.025305 mol H₂O ≈ 0.0253 mol H₂O
The problem is based on Charles law.
The law states that, at constant pressure the volume occupied by an ideal gas varies directly with its temperature in Kelvin.
The equation for the law can be written as
We have been given that
V₁ = 8.98 dm³
V₂ = ?
T₁ = 38.8 °C.
To convert this to Kelvin , we add 273.15.
Therefore T₁ = 311.95 K
T₂ = 233.25 K
Let us plug the values in the Charles equation.
The gas will occupy 6.71 dm³ at -39.9 °C if the pressure remains constant.
