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.

i think so it’s will be b yes i believe its
