What are two properties of liquids, solids, gases and matter. What are two important things about them.
larisa86 [58]
Solids— have tightly packed molecules, structured shape

Liquid— have no definite shape and the molecules are not tightly packed like a solid, they are a lot more loose.

Gas— No structure at all, molecules are free flowing

Sorry I couldn’t be a better help.. but I hope this gives you a bit of an idea :)

You are trying to determine the volume of the balloon needed to match the density of the air in the lab. You know that if you ca
vova2212 [387]
The equation to be used are:

PM = ρRT
PV = nRT
where
P is pressure, M is molar mass, ρ is density, R is universal gas constant (8.314 J/mol·K), T is absolute temperature, V is volume and n is number of moles

The density of air at 23.5°C, from literature, is 1.19035 kg/m³. Its molar mass is 0.029 kg/mol.

PM = ρRT
P(0.029 kg/mol) = (1.19035 kg/m³)(8.314 J/mol·K)(23.5+273 K)
P = 101,183.9 Pa

n = 0.587 g * 1 kg/1000 g * 1 mol/0.029 kg = 0.02024 mol
(101,183.9 Pa)V = (0.02024 mol)(8.314 J/mol·K)(23.5+273 K)
Solving for V,
V = 4.931×10⁻⁴ m³
Since 1 m³ = 1000 L
V = 4.931×10⁻⁴ m³ * 1000
V = 0.493 L
