How many moles of oxygen did the student collect?

abb0t · Answer

use the ideal gas law formula: PV = nRT 
P=pressure
V = volume
n = mole
R = gas constant
T = temp

your units depend on your "R" units. 

rearrange to solve for "n" using the tricks you learned in basic algebra.

anonymous · Answer

@abb0t p=0.899
v=?
n=626mL
r=?
and t=24 degrees C

anonymous · Answer

@abb0t how do I find v and r?

anonymous · Answer

@primeralph any chance u remember this?

primeralph · Answer

Yeah.

abb0t · Answer

you're already given V (volume)!!!
and "R" is a constant that is already given to you, you can find it in your book.

anonymous · Answer

or is 625mL the volume?
