2H202-> 2H2O + O2

Suppose you carry out the decomposition using 25.0 mL of a 2.00M hydrogen peroxide solution and obtain the following: 8.62 mL of gas is collected in 120 seconds. How many moles of oxygen are produced per second?
Answered by Steve
well, at STP, 1 mole is 22.4L, so

8.62mL = 8.62/22400 moles

1/3 of that is O2, no?

No temperature is listed in the problem but usually this is at room T; therefore, the only gas is O2.
