Answer: density, Omass, radiation, pressure because  Radiation pressure is the mechanical pressure exerted upon any surface . Small bodies are more affected than large ones because of their lower mass relative to their surface area formed by the radiation pressure of the young stars reduces the cluster mass enough to allow rapid dispersal.

Explanation: I Hope that helped!!!

Calculate the volume of 5.00 mol of helium at 120C and 1520 mm Hg
levacccp [35]

Answer:

80.7 L

Step-by-step explanation:

This looks like a case where we can use the Ideal Gas Law to calculate the volume.

pV = nRT       Divide both sides by p

V = (nRT)/p

=====

Data:

n = 5.00 mol

R = 0.082 06 L·atm·K⁻¹mol⁻¹

T = (120 +273.15) K = 393.15K

p = 1520 mmHg × 1 atm/760 mmHg = 2.00 atm

=====

Calculation:

V = (5.00 × 0.082 06 × 393.15)/2.00

V = 161.3/2.00

V = 80.7 L
