Question #171351

A sample of B_{2}H_{6} gas in a 35.0-mL container is at a pressure of 450. mm Hg and a temperature of **571** °C. If the gas is allowed to cool at constant volume until the pressure is **354** mm Hg, what is the new temperature in °C?

Expert's answer

"\\frac{P_1}{T_1}=\\frac{P_2}{T_2}"

="\\frac{450}{844}=\\frac{354}{T_2}"

="T_2=\\frac{844\u00d7354}{450}" =663.95K

"T_2=390.95^{o}C"
