Answer: The pressure exerted by the gas, in atm is 1.092
Explanation:
According to the ideal gas equation:'
P = Pressure of the gas = ?
V= Volume of the gas
T= Temperature of the gas = (0°C = 273 K)
n= moles of gas =
R= Value of gas constant = 0.0821 Latm/K mol
as
where d is density
Thus pressure exerted by the gas, in atm is 1.092
14,400 gallons of water can be filtered by the new water filter invented by the company.
It is given that the filter can process 10 gallons of water per minute.
So In an hour:
10 gallons per minute x 60 minutes = 600 gallons in 1 hour.
And in a day:
24 hours x 600 gallons per hour = 14,400 gallons in 24 hours.
Hence, 14,400 gallons of water can be filtered.

Answer:
The Ka value used for the buffer system is :- Ka2 = pKa2 = 7.2
pH = 7.1
Explanation:
The buffer system given in the question is :-
and
The reaction taking place is:-
The Ka value used for the buffer system is :- Ka2 = pKa2 = 7.2
The pH can be calculated as:-
pH = 7.2 + log 0.40/0.50 = 7.1
answer: D
