Answer : The initial temperature of gas would be, 269.7 K

Explanation :

Combined gas law is the combination of Boyle's law, Charles's law and Gay-Lussac's law.

The combined gas equation is,

\frac{P_1V_1}{T_1}=\frac{P_2V_2}{T_2}

where,

P_1 = initial pressure of gas = 0.723 atm

P_2 = final pressure of gas = 0.612 atm

V_1 = initial volume of gas = 13.5 L

V_2 = final volume of gas = 17.8 L

T_1 = initial temperature of gas = ?

T_2 = final temperature of gas = 28^oC=273+28=301K

Now put all the given values in the above equation, we get:

\frac{0.723atm\times 13.5L}{T_1}=\frac{0.612atm\times 17.8L}{301K}

T_1=269.7K

Thus, the initial temperature of gas would be, 269.7 K

Which of the following measurements is equal to 2.3 dL?
Verdich [7]
2.3 dL = .23 liters. d=deci=10^-1 so you move the decimal place back once.

It's D because micro is 10^-6 (move the decimal place back 6 times) 230,000x10^-6=.23 liters or 2.3 dL.
