Question

What volume would a liter of gas, measured at 273 K, occupy if it is heated to 100⁰C, the pressure remaining
constant? Show the calculation.

Answer 1

Answer:

If you noticed, we calculated the value of the proportionality constant R based on the fact that exactly one mole of a gas at exactly 1 atm and at 0 ˚C (273 K) has a volume of 22.414 L. This is one of the “magic numbers in chemistry; exactly one mole of any gas under these conditions will occupy a volume of 22.414 L.

Get familiar with the ideal gas law. It can be written as: V = nRT/P. "P" is pressure, "V" is volume, n is the number of moles of a gas, "R" is the molar gas constant and "T" is temperature.
