KE=.5mv^2
M=mass
v=velocity
.5(4)(100)=200
That should be the answer.
It’s the process of detecting a change of a objects position relative to its surroundings
Answer:
Volume of 6.5 moles of Helium at STP is 145.6954 L
Explanation:
As we know
At STP, temperature is 273.15 K and pressure is 1 atm
n is the number of moles which is equal to 6.5
R is the gas constant = 0.08206 L atm/K mol
Substituting the given values in above equation, we get -
Liters
Volume of 6.5 moles of Helium at STP is 145.6954 L
Answer:
235L
Explanation:
PV =nRT
V = nRT/P
47.20 °C is 320.35K
V = (79.5 mol)(0.0821 atm•L/mol•K)(320.35K)/8.91atm
V = 234.6698577L
Round to 3 sig figs: 235L
