Question #5d932
1 Answer
Explanation:
We're asked to find the original volume of
To do this, we can use the pressurevolume relationship of gases, illustrated by Boyle's law:
where

#P_1# is the original pressure, given as#900.# #"torr"# 
#V_1# is the original volume (what we're trying to find) 
#P_2# is the final pressure, given as#1.5# #"atm"# 
#V_2# is the final volume, given as#250.# #"mL"#
We need the units for pressure to be consistent, so let's convert the
Plugging in known values, and solving for the original volume,
which I'll round to
