Ten to the negetive third power L over 1 mL
1. The student didn’t push with enough force ._.
Answer:
Explanation:
<u>1) Data:</u>
a) T = 25°C = 25 + 273.15K = 298.15 K
b) P = 1 atm
c) assumption: ideal gas
<u>2) Formulae and principles</u>
a) Ideal gas equation: p V = n R T, where:
- p = pressure
- V = volume
- n = number of moles
- R = universal constant of gases = 0.0821 atm-liter / K-mol
- T = absolute temperature (Kelvin)
b) Molar volume: ν = V / n, where:
- ν = molar volume
- V = volume
- n = number of moles
<u>3) Solution:</u>
- p V = n R T⇒ V/n = ν = RT / p =
= 0.0821 atm-liter / mol-K × 298.15 K / 1 atm
= 24.5 liter / mol
