A gas cylinder is filled with argon at a pressure of 177 atm and 25°C. What is the gas pressure when the temperature of the cyli
Elena L [17]

277.79 atm is the calculated gas pressure.

The ideal gas is a fictitious concept used to study how real gases behave by comparing them to their deviations. The pressure-temperature rules are followed by an ideal gas.

177 atm is the initial pressure. The starting temperature is 298 K (25 °C = 25 + 273 °C).

195°C = 195+273

= 468K is the final temperature.

The pressure temperature relation illustrated below can be used to get the final pressure.

P1/T1 = P2/T1

= P1T2/T1

= 177 atm 468 K /298 K

= 277.97 atm

The final pressure is therefore 277.97 atm.

andrezito [222]

Answer:

6

Explanation:

6H2O2

H2=6×2=12

O2=6×2=12

H2=12×1   =     12

O2=12×16= +192

               =  204  

=204÷34=6 ANS
