Answer:

3.5 atm

Explanation:

Given data

  • Initial pressure (P₁): 47.9 atm
  • Initial volume (V₁): 21 L
  • Final pressure (P₂): ?
  • Final volume (V₂): 290 L

We can find the maximum pressure that the gas can exert (final pressure) using Boyle´s law.

P₁ × V₁ = P₂ × V₂

P₂ = P₁ × V₁ / V₂

P₂ = 47.9 atm × 21 L / 290 L

P₂ = 3.5 atm

water’s molar mass is 18.01 g/mol. The molar mass of glycerol is 92.09 g/mol. At 25 celsius, glycerol is more viscous than water
Gemiola [76]

Answer is: glycerol because it is more viscous and has a larger molar mass.

Viscosity depends on intermolecular interactions.

The predominant intermolecular force in water and glycerol is hydrogen bonding.

Hydrogen bond is an electrostatic attraction between two polar groups in which one group has hydrogen atom (H) and another group has highly electronegative atom such as nitrogen (like in this molecule), oxygen (O) or fluorine (F).
