A gaseous mixture contains 5.0 moles of nitrogen and 10.0 moles of helium . What is the total pressure if the temperature is 25
jolli1 [7]

Answer:

A) 122 atm

Explanation:

PV = nRT

Solve for P --> P = nRT/V

n = 10.0 mol + 5.0 mol = 15.0 mol

R = 0.08206 L atm / mol K

T = 25 + 273 = 298 K

V = 3.0

P = (15.0)(0.08206)(298) / (3.0) = 122 atm

Which weather is most likely to occur? Help please
Shtirlitz [24]
Well usually a tornado forms when hot air and cold air come together and in the south, but since the weather is cold and they live by mountains a tornado would not happen.

A hurricane happens by the ocean.

I believe the answer would be a rainstorm.   <span />
