The O2(g) produced from the decomposition of the 1.0 L sample of H2O2(aq) is collected in a previously evacuated 10.0 L flask at 300. K.

What is the approximate pressure in the flask after 400. s?

(For estimation purposes, assume that 1.0 mole of gas in 1.0 L exerts a pressure of 24 atm at 300.K.)

It could possibly be beneficial if the experiment is successful.

Ithink that’s it’s b
