In chemistry, the molar mass of a chemical compound is defined as the mass of a sample of that compound divided by the amount of substance in that sample, measured in moles. It is the mass of 1 mole of the substance or 6.022×10²³ particles, expressed in grams.

Answer:
200.6cm³
Explanation:
Using Charles law equation as follows:
V1/T1 = V2/T2
Where;
V1 = initial volume (cm³)
V2 = final volume (cm³)
T1 = initial temperature (K)
T2 = final temperature (K)
According to the question;
initial volume (V1) = 254cm³
final volume (V2) = ?
Initial temperature (T1) = 72.6°C = 72.6 + 273 = 345.6K
Final temperature (T2) = 273K
V1/T1 = V2/T2
254/345.6 = V2/273
Cross multiply
345.6 × V2 = 273 × 254
345.6V2 = 69342
V2 = 69342 ÷ 345.6
V2 = 200.6cm³
