At what temperature will 6.21 g of oxygen gas exert a pressure of 5.00 atm in a 10.0-L container?

Sagot :

PV = nRT
P = 5 atm
V = 10 L

molecular mass of oxygen gas = 16 X 2 =32 g/mole

so number of moles of oxygen gas =

6.21/32 = 0.194
so n = 0.194
R = 0.0821 L atm K^-1 mole^-1
T = ? K



5 X 10 = 0.194 X 0.0821 X T

50 = 0.0159 X T

T = 50/0.0159 = 3144.654 K

in degree c = 3144.654 - 273
= 2871.65 degree c

Answer:The value of the temperature is 2,870.072°C.

Explanation:

Moles of oxygen = n =[tex]\frac{6.21 g}{32 g/mol}=0.1940 mol[/tex]

Pressure of the gas = 5.00 atm

Volume of the gas = 10.0 L

Temperature of the gas = T

[tex]PV=nRT[/tex]

[tex]5.00 atm\times 10.0L=0.1940 mol\times 0.0820 atm L/mol K\times T[/tex]

[tex]T=\frac{5.00 atm\times 10.0L}{0.1940 mol\times 0.0820 atm L/mol K}=3,143.072 K=2,870.072^oC[/tex]

(T(K)=T(°C)-273)

The value of the temperature is 2,870.072°C.
