Answer:
0.0821 atm.L/Kmol
Explanation:
At stp, the values temperature, pressure and volume is given below:
Pressure (P) = 1 atm
Temperature (T) = 273 K
Volume (V) = 22.4 L
At stp, 1 mole of a gas occupy 22.4L.
Number of mole (n) = 1 mole
Gas constant (R) =?
The ideal gas equation is given below:
PV = nRT.
With the above equation, the gas constant R can be obtained as follow:
1 atm x 22.4L = 1 mole x R x 273K
Divide both side by (1 mole x 273 K)
R = (1 atm x 22.4L) / (1 mole x 273 K)
R = 0.0821 atm.L/Kmol
Therefore, the gas constant is 0.0821 atm.L/Kmol
Answer:
a
Explanation: took it on in class
Yes because a chemical reaction will change the weight and mass of an object but all the molecules did not dissapear. they were just formed into a different substance, wether that being a solid, liquid, or gas.
