Answer:
V = 11.2 L
Explanation:
Hello there!
In this case, according to the ideal gas equation:
It is possible to compute the volume as shown below:
Whereas the moles are computed are computed given the mass and molar mass of oxygen:
Now, since the STP stands for a temperature of 273.15 K and a pressure of 1 atm, the resulting volume is:
Best regards!
"-2" is the electric charge of the oxygen ion among the following choices given in the question. It actually needs two electrons to complete the stable outer shell. The correct option among all the options that are given in the question is the third option or option "C". I hope that the answer has helped you.

Answer/Explanation:
Methanol has a molecular weight (32.04 g/mol), low-boiling point and because of its low boiling point, methanol readily evaporates at room temperature.
Under these specified non-standard conditions, the partial pressure of methanol is lower than its vapor pressure and this explains the reason for the spontaneous evaporation exhibited by methanol.
Heterogenous mixtures are unevenly mixed. Like oil and vinegar in vinaigrette if it is not emulsified well enough and they separate. Any case where two things are not evenly distributed within each other.
Homogenous mixtures are evenly mixed throughout. Like salt water or kool-aid (when it's mixed).
Hope this helps!
