Answer:
280 mL
Explanation:
Ideal gas law:
PV = nRT
Rearranging:
V / T = nR / P
At constant pressure:
V₁ / T₁ = V₂ / T₂
Substituting values:
250 / (15 + 273) = V / (45 + 273)
V = 276
Rounded to two significant figures, the volume will be 280 mL.
When using the ideal gas law, remember to always use absolute units for temperature, like Kelvin.

Question
what is a molecular Solid
Answer:
A molecular solid is a type of solid in which molecules are held together by van der Waals forces rather than by ionic or covalent bonds.
Explanation:
A molecular solid is a solid consisting of discrete molecules. The cohesive forces that bind the molecules together are van der Waals forces, dipole-dipole interactions.
