Amixture of three gases, a, b, and c, is
at a total pressure of 7.47 atm. the partial
pressure of gas a is 1.59 atm; that of gas b is
3.78 atm. what is the partial pressure of gas
c?
answer in units of atm

2.1 atm is the partial pressure of gas C.

Explanation:

to calculate partial pressure of gas  C we will use Dalton's law.

According to the Dalton's law, the total pressure of the gas is equal to the sum of the partial pressure of the mixture of gasses.

where,

= Total pressure

= partial pressure of gas-1

= partial pressure of gas-2

= partial pressure of gas-3

= partial pressure of nth gas in the mixture

We have:

Now put all the given values is expression, we get the partial pressure of the gas.

2.1 atm is the partial pressure of gas C.

in 1783 cavendish was working with his hydrogen gas and found that when he burned it and condensed the vapor it was water. this was very significant since it disproved the greek theory of elements completely since water was not a simple substance but the product of two gases. it was lavoisier who hearing of the experiment gave cavendish's gas the name hydrogen ("water-producer") and added that hydrogen burned by combining with oxygen and that water was a hydrogen-oxygen combination.
