Question

Use the following formula to compute the partial pressure of the butane.

Pbutane = Atmosphere - Pwater

Answer 1

Pbutane = (770.7 mm Hg) – (39.9 mm Hg)
Pbutane = 730.8 mm Hg

Answer 3

It's correct if it is given that the butane is mixed with moisture at atmospheric pressure.
Don't know if the pressures are given or calculated.

Answer 4

1. Since the gas in your graduated cylinder is a mixture of butane and water vapor, you must determine the partial pressure of the butane, Pbutane, alone. To do this, consult a reference and record the partial pressure of the water vapor, Pwater, at the temperature you recorded. Use the following formula to compute the partial pressure of the butane.

Answer 5

thats the whole question do u want the chart i did already?

Answer 6

So the temperature is about 34 degrees?

Answer 7

yes

Answer 8

Yes, the vapour pressure is correct, and the rest as well.

Answer 9

I mean 34 degrees Celsius?

Answer 10

That is true only if there is nothing but butane and H2O.

Answer 11

yes but how do compute the partial pressure of the butane.

Answer 12

so what do you want me to put the answer as? @mathmate

Answer 13

@danJS

Answer 14

Is this what you are using?

Answer 15

yea

Answer 16

what do you think it is

Answer 17

I think you did it correctly at the top... just use the formula they give you ..
Partial pressure of butane = Atmosphere pressure - Partial Pressure of water

Answer 18

Using the values at whatever temperature you have
