A mixture of two gases has a total pressure of 5.7 atm . If one gas has a partial pressure of 4.1 atm , what if the partial pres
2 answers:
Answer:
1.6 atm
Explanation:
We are given that total pressure of mixture of two gases=5.7 atm
Partial pressure of one gas=4.1 atm
We have to find the partial pressure of other branch.
We know that Dalton;s law of partial pressure
It states that pressure exerted by mixture of gases is equal to sum of partial pressure exerted by gases in mixture.
Let x bet the pressure exert by other gas
Apply this law
Total pressure=4.1+x
Hence, the partial pressure of other gas=1.6 atm.

Given ,
Mass of sample of cobalt = 27 g
density of sample of cobalt = 9g/cm^3
We know that ,
Density = mass of sample/volume of sample
From that relation ,
We can deduce the following as
Volume = mass of sample/density of sample
Hence , required volume of sample of cobalt = 27 g /9 g/cm^3 = 3 cm^3
The volume is
Mass of sample of cobalt = 27 g
density of sample of cobalt = 9g/cm^3
We know that ,
Density = mass of sample/volume of sample
From that relation ,
We can deduce the following as
Volume = mass of sample/density of sample
Hence , required volume of sample of cobalt = 27 g /9 g/cm^3 = 3 cm^3
The volume is
