Answer:
The volume of the gas under the new conditions is 266 ml
Explanation:
We use the gas formula, which results from the combination of the Boyle, Charles and Gay-Lussac laws. According to which at a constant mass, temperature, pressure and volume vary, keeping constant PV / T. We convert the unit Celsius into Kelvin:
0 ° C = 273K, 45 ° C = 273 + 45 = 318K. The conditions STP are: 1 stm of pressure and 273K of temperature.
P1xV1/T1= P2xV2/T2
1 atmx 251ml/273K=1,10atmx V2/318K
0,92 atmx L/K = 1,10atmx V2/318K
V2= (0,92 atmx L/K x 318K)/1,10 atm= 265, 79 ml
