Asample of gas contains 6.25 × 10^-3 mol in a 500.0 ml flask at 265°c. what is the pressure of the gas in kilopascals?

solve the problem for the pressure of oxygen.

55.73 kPa

Explanation:

Using ideal gas law :

P = pressure of the gas=?

V = volume of the gas = 500 ml = 0.5L

T = temperature of the gas =

n = number of moles of the gas=

R = gas constant = 0.0821 Latm/moleK

(1 atm =101.325kPa)

space exploration has led to the development and technological improvement of many everyday items. (if this answer is wrong i will find the right answer) : )

there are two significant figures.
