The volume of a gas is 22 mL at 44°C and
sveticcg [70]

Answer:

The volume will be 18,23 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,  44+273=317K, 17+273=290 K. The volume in L= 22/1000= 0,022L

P1xV1/T1= P2xV2/T2

V2= ((P1xV1/T1)xT2)/P2

V2=((0,905 atm x 0,022L/317K)x 290K)/0,999atm= 0,01823 L

0,01823x 1000= 18, 23 ml
