1l of n_2_ gas, having a pressure of 2.5 atm, is added 1 l of ar gas, having a pressure of 3.7 atm, in a sealed, rigid flask. what is the final pressure in the flask?

P(total) = 6.2 atm

Explanation:

Given data:

Pressure of nitrogen = 2.5 atm

Pressure of argon = 3.7 atm

Final pressure = ?

Solution;

According to Dalton law of partial pressure,

The total pressure exerted by mixture of gas is equal to the sum of individual pressure of each gas present in mixture.

Mathematical expression:

P(total) = P₁ + P₂+ Pₙ

Now we will put the values in formula:

P(total) = P₁ + P₂

P(total) = 2.5 atm + 3.7 atm

P(total) = 6.2 atm

answer: at room temperature (roughly 20 degrees c), you can dissolve 203.9 grams (or 200 grams) of sugar in 100 ml of water. as water temperature increases, the amount of sugar that will dissolve increases, up to about 500 grams of sugar in 100 ml water at 100 degrees c.
