Answer: The number of molecules of gas the flask contains is
Explanation:
According to ideal gas equation:
P = pressure of gas = 1 atm (STP)
V = Volume of gas = 2.50 L
n = number of moles = ?
R = gas constant =
T =temperature = 273K (STP)
According to Avogadro's law:
1 mole of gas at STP contains = molecules
Thus 0.112moles of gas at STP contains = molecules
The number of molecules of gas the flask contains is

204 can be factored into 2 and 102, then 102 can be factored into 1 and 51, and then 51 can be factored into 3 and 17. So then you would get 2*3*17*1.
