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.
