What volume will 454 grams (1 lb) of hydrogen occupy at 1.05 atm and 25 #"^o#C?
1 Answer
Explanation:
We're asked to find the volume occupied by
To do this, we can use the idealgas equation:
where

#p# is the pressure, in units of#"atm"# (given as#1.05# #"atm"# ) 
#V# is the volume the gas occupies, in units of#"L"# (we'll be finding this) 
#n# is the number of moles of the gas present (we'll need to convert the given mass in grams to moles) 
#R# is the universal gas constant, equal to#0.082057("L"·"atm")/("mol"·"K")# 
#T# is the absolute temperature of the gas, in units of#"K"# (given#25# #""^"o""C"# )
We need to do some conversions:
Let's find the number of moles of
The temperature in
Plugging in known values, and solving for the volume,
