Answer:
5.73 × 10⁶ L
Solution:
As we know one cubic foot is equal to 28.3168 L. Using this relation we can convert 2.027 × 10⁵ ft³ into L as,
1 ft³ = 28.3168 L
So,
2.027 × 10⁵ ft³ = X L
Solving for X,
X = (2.027 × 10⁵ ft³ × 28.3168 L) ÷ 1 ft³
X = 5.73 × 10⁶ L
H-1 only has 1 proton and 1 electron, so its mass number is 1.
H-2 has one more neutron so its mass number is 2
H-3 has one more neutron than H-2 so its mass number will be 3.
average atomic mass = 1 x 99% + 2 x 0.8% + 3 x 0.2%
=1.012
Answer:
557.3J is the work of expansion of the CO2 gas
Explanation:
The work of expansion of a gas under constant temperature and pressure (Isobaric pressure) is:
W = P*ΔV
<em>Where W is work</em>
<em>P is pressure = 1.0atm</em>
<em>ΔV = Final volume - Initial Volume = 6.5L - 1.0L = 5.5L</em>
<em />
Replacing:
W = 1.0atm*5.5L
W = 5.5atmL
In Joules (1atmL = 101.325J):
5.5atmL * (101.325J / 1atmL) =
<h3>557.3J is the work of expansion of the CO2 gas</h3>
