This question is a very straight forward Question, we have given almost all the parameters needed to solve the question. The parameters given in the question are: Number of moles of oxygen gas = 2.80 mol, the volume of the cylinder= 8.58 L, pressure of the 02 = ???( not given) and the gas temperature = 294 K.
We are going to use the formula for the ideal gas law below to solve this question:
PV = nRT.
Where P = pressure, V = volume , n= number of moles, R= gas constant and T= temperature.
A cooked chicken would be somewhat burnt or cooked. A glass of kool aid would be mixed, or aka homogenous mixture. The glass would maintain a color, because its not water.
