Explanation:
The mass of air in the scuba tank is 841.614 g.
Using the ideal gas equation;
PV=nRT
P = pressure of the gas = 195 kPa
V = volume of the gas = 350 L
n = Number of moles of the gas = ??
R = molar gas constant = R = 8.314 J K-1 mol-1
T = temperature of the gas = 10 °C or 283 K
n = PV/RT
n = 195 * 350/8.314 * 283
n = 68250/2352.862
n = 29.00 moles
Number of moles = mass/molar mass
mass of air = Number of moles * molar mass
mass of air = 29.00 moles * 29g/mol
Mass of air = 841.614 g

Answer:
A Semipermeable membrane is a type of biological or synthetic, polymeric membrane that will allow certain molecules or ions to pass through it by diffusion or occasionally by more specialized processes of facilitated diffusion, passive transport or active transport.
I'm not sure where the question is here. Yes it is true that there is a limited amount of matter on Earth...
