Molar mass of COH1206 is 1243.5857 g/mol
Answer is: volume of CO₂ is 0,113 dm³.
Ideal gas law = pV = nRT.
p = 850 PSI = 5860543,6992 Pa.
Psi <span>is the abbreviation of pound per square inch.
T = 21</span>°C = 294,15 K.
n = 0,273 mol.
R = 8,314 J/K·mol.
V = nRT ÷ p
V = 0,273 mol · 8,314 J/K·mol · 294,15 K ÷ 5860543,6992 Pa.
V = 0,00011 m³ = 0,113 dm³.
B) When describing very dilute solutions.
Explanation:
The most appropriate time to use ppm is when describing dilute concentrations of solutes in solutions. It is used mostly to determine trace amount of elements in water and soils.
- The part per million ppm is the amount of miligram of a solute in a liter of solution.
- It is similar to percentage.
- Minute and trace concentrations are very difficult to work with.
- Using parts per million, they become better appreciated and easy to use.
