Question

A gas is at a pressure of 4.30 atm. what is this pressure in kilopascals? in mm hg?

Answer 1

Units to measure pressure are as follows
atm - atmospheric pressure units
kPa - kilo Pascals
mm Hg - milimeters Hg
conversion units are;
 1 atm = 101 325 Pa
therefore 4.30 atm = 101 325 Pa / atm x 4.30 atm = 435.7 Pa

1 atm = 760.0 mm Hg
 4.30 atm = 760.0 mm Hg / atm x 4.30 atm = 3268 mm Hg

answers are 435.7 Pa and 3268 mm Hg

Answer 2

Answer:

Explanation:

The rule of three or is a way of solving problems of proportionality between three known values and an unknown value, establishing a relationship of proportionality between all of them. That is, what is intended with it is to find the fourth term of a proportion knowing the other three. Remember that proportionality is a constant relationship or ratio between different magnitudes.

If the relationship between the magnitudes is direct, that is, when one magnitude increases, so does the other (or when one magnitude decreases, so does the other) , the direct rule of three must be applied. To solve a direct rule of three, the following formula must be followed:

a ⇒ b

c ⇒ x

Then

$x=\frac{c*b}{a}$

In this case you know:

1 atm= 101.325 kilopascals

1 atm = 760 mm Hg

The rule of three applies as follows: if 1 atm is 101,325 kilopascals, 4.30 atm what is the pressure in kilopascals?

$pressure=\frac{4.30 atm*101.325 kilopascals}{1 atm}$

pressure=435.6975 kilopascals

The rule of three applies as follows: if 1 atm is 760 mmHg, 4.30 atm what is the pressure in mmHg?

$pressure=\frac{4.30 atm*760 mmHg}{1 atm}$

pressure=3,268 mmHg
