Question

oxygen used in hospitals and laboratories is often obtained from cylinders containing liquefied oxygen. a cylinder contained 1.00 x 10^2kg of liquid oxygen. the volume(litters) of oxygen that could produced at 1.00atm of pressure at room temperature, 20.0 degree celcius is, (atomic mass of O=16g, R=0.08205 L atm mol^-1 K^-1)

Answer 1

Whats your question?

Answer 2

the volume(litters) of oxygen that could produced at 1.00atm of pressure at room temperature, 20.0 degree celcius is @Abmon98

Answer 3

1*10^5*V=0.08205*(273+20)*(1*10^2*10^3/16)

Answer 4

1*10^2*10^3/16)
this part that 16 is divide by 10^3 only or the whole bracet? @Abmon98

Answer 5

nope the whole bracket because we need to change the kg into grams to get the number of moles

Answer 6

the answer u gt was it 1.5025??

Answer 7

yes exactly

Answer 8

but this answer is not in the choices given!!
A. 75.2X10^2 L
B. 75.2X10^3 L
C. 0.752 L
D. 75.2 L
E. 7.52 L

Answer 9

Use PV = nRT

Answer 10

I get B as my answer.

Using PV=nRT and solving for V:

P = 1 atm
n = 100 000 g / 32 g/mol = 3125 mol
R = 0.08206
T = 293 K
