# Chem HW Help!

I need help answering some questions on how to combine gas law.If for some reason you don't feel you shold answer this question can you provided me with the steps on how to combine gas laws or give me a good website that may provided help or may have a good combine gas law calculator.

1. I just remember two gas laws. The general one is PV = nRT. The other one is
P1V1/T1 = P2V2/T2 which I use when no number of mols is given.

I also remember that 1 mol of a gas at STP occupies 22.4 L.
Nothing to combine that way. But if you will post a specific question, perhaps we still can help.

2. The gas law that I'm refering to is P1v1/T1=P2V2/T2. The question that I have to answer is:
P1V1/T1=P2V2/T2

P1

600 mm Hg = an answer in the blank bok that I was not able to provide.
atm (round to hundredths place)

V1

24 mL = an answer in the blank bok that I was not able to provide.

L (round to thousandths place)

T1

18 °C = an answer in the blank bok that I was not able to provide
K

P2

430 mm Hg = an answer in the blank bok that I was not able to provide

atm (round to hundredths place)

v2 = ? with an answer that is suppose to be placed in a black box underneath the v1.
L (round to thousandths place)

T2
24 °C = an answer in the blank bok that I was not able to provide.

K.

3. The gas law that I'm referring to is P1v1/T1=P2V2/T2. The question that I have to answer is:

P1

The question wants you to convert mm Hg pressure to atmospheres. The conversion factor is 1 atm = 760 mm Hg. So 600/760 = ?? atm.For what it's worth, pressure can be in any unit, with this formula, as long as you keep the units consistent; i.e., if you use P1 in atm then P2 must be in atm or if you use P1 in mm Hg then P2 must be in mm Hg.

V1

24 mL = an answer in the blank bok that I was not able to provide.

L (round to thousandths place)
The question wants you to convert 24 mL to liters. You know that 1000 mL = 1 L. You convert by 24 mL x (1 L/1000 mL) = ??

T1

18 °C = an answer in the blank bok that I was not able to provide
K Kelvin = 273 + C

P2

430 mm Hg = an answer in the blank bok that I was not able to provide

atm (round to hundredths place)
Converted the same say as P1 above.

v2 = ? with an answer that is suppose to be placed in a black box underneath the v1.
L (round to thousandths place)
I assume you are to calculate V2 since you have all but that one number.

T2
24 °C = an answer in the blank bok that I was not able to provide.
Kelvin = 273 + C.
K.

This is more a question of how to use conversion factors than it is a question a gas laws.
