For the combining gas law P1V1/T1=P2V2/T2 home work assignment I did three answers on my own and would like you to check them if they are right. If for some reason the answers that I provided don't seem correct please provide me with the right answers.

P1V1/T1=P2V2/T2

For number 1 these are the answers that I provided.

P1V1/T1=P2V2/T2

P1 was 600 mm Hg and underneath it was a blank box. In the blank box I plug in the answer 700 atm because the answer had to be rounded to the hundredths place.

V1 was 24 mL and underneath it was a blank box in which I plug in 4000 L as my answer because the answer that I got needed to be rounded to the thousandths place and that was how I got my answer.

T1 was 18 °C and underneath it was a blank box in which I plug in 291 K as my answer because I used 273 + 18= 291 as my answer.

P2 was 430 mmHg and underneath it was a blank box in which I plug in the answer 500 atm because the regular answer that I got had to be rounded to the nearest hundredths place and that was how I got 500 atm as my answer.

V2 was a ?

T2 was 24 °C and underneath it was a blank box. I used 273 + 24 °C = 297 K as my answer.

For number 2 these are the answers that I provided.

P1V1/T1=P2V2/T2

P1 was a ?

V1 is 1.6 L.

T1 was 25 °C and underneath it was a blank box. I used 273 + 25 °C = 298 K as my answer.

P2 was 1.2 atm.

V2 was 2.2 L.

T2 was 10 °C and underneath it was a blank box in which I plug in 7 K as my answer after I rounded my regular answer to the ones place.

For number 3 these are the answers that I provided.

P1V1/T1=P2V2/T2

P1 was 95 kPa and underneath it was a blank box in which I provided 100 atm as my rounded answer to the hundredths place.

V1 was 224 mL and underneath it was a blank box in which I plug in the answer 1000 L as my rounded answer to the thousandths place.

T1 was 374 K.

P2 was 125 kPa and underneath it was a blank box in which I plug in the answer 700 atm as my rounded answer to the hundreds place.

V2 was 450 mL and underneath it was a blank box in which I plug in the answer 6000 L as my rounded answer to the thousandths place.

T2 was a question mark and underneath it was a blank box but I provided 7 as my rounded answer to the ones place.

How do I combine the gas law for these questions.

1. I have to say your answers make no sense at all. Consider this number..

ABCD.EFG

F is the hundredths place
G is the thousandths place.

Your description is a great variance to this.

2. Lizy--What you are missing here is the concept. I worked this problem yesterday in detail. I thought it was for you but it may have been for another student. The 600 mm number is the pressure. The black box to which you refer is the answer box and the teacher wants this number of 600 mm Hg pressure converted to atmospheres. The conversion factor is 760 mm Hg pressure = 1 atmosphere pressure; therefore, 600/760 = 0.789473684211 atm. THIS is the number to be rounded to the hundredths place (not the 600 number). Therefore, this number, rounded to the hundredths place is 0.79 atm.
The other parts of the problem are done the same way. Your conversions for C to Kelvin are done properly although I didn't check the addition. The volume, in mL, is to be converted to liters and THAT is the number to be rounded, not the 24. If you will redo your problem and repost it (please only one problem to a post) we shall be happy to take another look at it. If you are having a problem with the conversions, perhaps you should post an example and tell us what you don't understand about it.
