Answer:
5528 balloons
Explanation:
Explanation:
At constant pressure and number of moles, using Boyle's law
Given ,
V₁ = 155.0 L
V₂ = ?
P₁ = 1835 psi
P₂ = 1 atm = 14.7 psia
Using above equation as:
Volume of each balloon = 3.5 L
Thus, number of balloons,

Iodine has 53 protons and 74 neutrons
I am assuming that the problem ask for the pressure in
the system. To be able to calculate this, we first assume that the system acts
like an ideal gas, then we can use the ideal gas equation to find for pressure
P.
P V = n R T
where,
P = Pressure (unknown)
V = 0.17 m^3
n = moles of lng / methane
R = gas constant = 8.314 Pa m^3 / mol K
T = 200 K
We find for the moles of lng. Molar mass of methane = 16
kg / kmol
n = 55 kg / 16 kg / kmol
n = 3.44 kmol CH4 = 3440 mol
Substituting all the values to the ideal gas equation:
P = 3440 mol * (8.314 Pa m^3 / mol K) * 200 K / 0.17 m^3
P = 33,647,247 Pa

Explanation:
Since [H+] [OH-] =10^(-14)
[H+] = (10^-14) / (1.4×10^-10)
