Question

What is the pressure, in atmospheres, of 6.0 grams of H2 gas if it has a volume of 73 liters when the temperature is 25° C?

0.50 atm
0.060 atm
1.0 atm
2.0 atm

Answer 2

The Ideal Gas Law ( PV = nRT ) is unlike the other gas laws in that it does not have an initial and a final state, meaning it does not need the situation to CHANGE in order to determine a value for Pressure, Volume, amount of gas or Temperature.
We can determine the Pressure, Volume, Temperature or amount of a gas (n) when the others are known. For this we must use Pressure in atmospheres, Volume in Liters, amount of gas in moles and Temperature in Kelvin.

Answer 3

what does n stand for?

Answer 4

for moles

Answer 5

oh

Answer 6

would the answer be 73 atoms?

Answer 7

nope @superhelp101
Pv=nrt
R=mass(g)/molar mass(g/mol)
R is a constant of 0.082 (atm*L/mole*K)
T stands for Temperature and is measured in kelvin
V stands for Volume and is measured in Litres
P is pressured is measured in atm

Answer 8

@superhelp101 I think you forgot to divide by 73 L

Answer 9

3moles x 0.0821L-atm/mole-K x 298K / 73L
pressure = 1 atom
???

Answer 10

yes thats right but put L-atm/mole-K in brackets

Answer 11

oh. i will. thank you very much :-)

Answer 12

your most welcome :D
