Jeff wants to find the volume of a gas in a cylinder. he knows that at 28°c and a pressure of 1 atm, the volume of the gas was 6.0 l. he measures the temperature and pressure and finds that the temperature is 39°c and the pressure has remained at 1 atm. what would be the best for jeff to use to find the volume of the gas?

by using ideal gas law

Explanation:

ideal gas law:

PV=nRT

where:

P is pressure measured in Pascal (pa)

V is volume measured in letters (L)

n is number of moles

R is ideal gas constant

T is temperature measured in Kelvin (K)

by applying the given:

P(initial) V(initial)=nRT(initial)

P(final) V(final)=nRT(final)

nR is constant in both equations since same gas

then,

P(initial) V(initial) / T(initial) = P(final) V(final) / T(final)

then by crossing multiply both equations

V (final)= { (P(initial) V(initial) / T(initial)) T(final) } /P (final)

P(initial)=P(final)= 1 atm = 101325 pa

V(initial)= 6 L

T(initial) = 28°c = 28+273 kelvin

T(final) = 39°c = 39+273 kelvin

by substitution

V(final) = 6.21926 L

for step 7 table c on the lab "newtons law of action"   the average time it took the car to travel .25 meters   was 1.92 seconds.

the average time it took the car to travel 0.50 meters was 2.61 seconds

hope this : )

> b takes place in the gas phase in an isothermal tubular reactor. the feed is one mole of a per one mole of c, an inert. the entering temperature and pressure are 427°c and 10 atm, respectively. the gas constant r = 0.08206 atm · l/mol · k.
