In an open vessel, the gas was heated so that its temperature increased threefold. How much gas was in the vessel if 0.24 kg of gas remained in the vessel at the end of heating?
To calculate the initial mass of the specified gas in an open vessel, we use the ratio: mn / mk = (P * V * M / (R * Tn)) / (P * V * M / (R * Tk)) = Tk / Tn, whence express: mn = mk * Tk / Tn.
Variables: mk – remaining gas mass (mk = 0.24 kg); Tc (temperature reached by the gas) = 3Tn (initial temperature).
Calculation: mn = mk * Tk / Tn = 0.24 * 3Tn / Tn = 0.24 * 3 = 0.72 kg.
Answer: The vessel initially contained 0.72 kg of the indicated gas.
