The answer is B) pure water because pure water is a poor conductor of electricity.. thus a poor electrolyte
Answer : The number of moles of gas present in container are 1.697 mole.
Explanation :
Using ideal gas equation,

where,
P = pressure of gas = 74 mmHg = 0.097 atm
conversion used : (1 atm = 760 mmHg)
V = volume of gas = 500.0 L
T = temperature of gas = 
n = number of moles of gas = ?
R = gas constant = 0.0821 L.atm/mole.K
Now put all the given values in the ideal gas equation, we get the number of moles of gas in the container.


Therefore, the number of moles of gas present in container are 1.697 mole.
Answer:
Atoms consist of three basic particles: protons, electrons, and neutrons. The nucleus (center) of the atom contains the protons (positively charged) and the neutrons (no charge). The outermost regions of the atom are called electron shells and contain the electrons (negatively charged).
