Answer: A.nitrogen,oxygen,and argon
Explanation:
Answer: 0.0624 atm
Explanation:-
According to the ideal gas equation:

P = Pressure of the gas = ?
V= Volume of the gas = 45.0 L
T= Temperature of the gas = -10.0°C = 263 K 
R= Gas constant = 0.0821 atmL/K mol
n= moles of gas
Moles of gas=

The pressure of sulfur hexafluoride gas in the reaction vessel after the reaction is 0.0624 atm
2000/18 =111.111111
111.1 moles
1 can of soda has 12 ounces * 2.01 mg/oz = 24.12 mg of caffeine.
1 gram = 1000 mg
10 grams x 1000 mg = 10,000 mg
Divide total mg by mg per can:
10,000 / 24.12 = 414.59 cans
Round to 415 cans
It should be 24.2624 because if there’s 2.72g in every cm3 and there are 8.92 cm3, then you simply multiply the two numbers
hope this helped :)
