If 10.0 liters of oxygen at STP are heated to 785.15 °K, what will be the new volume of gas if the pressure is also increased to
Ugo [173]

Answer: The new volume of gas is 28.5 L

Explanation:

The combined gas equation is,

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

where,

P_1 = initial pressure of gas = 1.00 atm (at STP)

P_2 = final pressure of gas = 102.6 kPa = 1.01 atm    (1 kPa= 0.0098 atm)

V_1 = initial volume of gas = 10.0 L

V_2 = final volume of gas = ?

T_1 = initial temperature of gas = 273.15K  (STP)

T_2 = final temperature of gas = 785.15K

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

\frac{1.00\times 10.0}{273.15}=\frac{1.01\times V_2}{785.15}

V_2=28.5L

The new volume of gas is 28.5 L

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
