Explanation:
To find the density of nitrogen gas at STP which is standard temperature and pressure, certain parameters must be known.
The mass of the gas must be given or its volume.
Density of a substance is the mass per unit area;
Volume of gas at STP = number of moles x 22.4
Using the volume obtained here,
Density = 
Then we can find the density.
The mass is very important.
Answer:
Partial pressure of Nitrogen = 0.6032 atm
Explanation:
According to Dalton's law of partial pressure, at constant temperature, the total pressure exerted by a mixture of gases that do not react with one another is a sum of the partial pressures of the individual gases. And the partial pressure of each gas is proportional to their percentage composition. The partial pressure of each as is given as
Partial Pressure = (Percentage composition) × (Total pressure)
In this question, a gas mixture of Carbon dioxide and Nitrogen exerts a total pressure of 1.04 atm
The mixture contains 42% CO₂, meaning it contains 100-42 = 58% of Nitrogen.
Partial Pressure of Nitrogen = 0.58 × 1.04 = 0.6032 atm
Hope this Helps!!!
