Question

P (atm) V (L) n (mol) T
5.08 (Fill in) 2.00 141 degress C

i need to fill in the volume PLEASE HELP. THANKS

Answer 1

I don't understand your problem. You have the numbers to substitute. T must be converted to Kelvin. You have one unknown. You are having trouble with what?

Answer 2

yes i need to fill in the unknown

Answer 3

Solve the equation. PV = nRT

Answer 4

i got 55.5. is that correct?

Answer 5

I don't get 55.5 with the data shown. What did you get for T? It should be 273+141. Another problem. The initial post has nothing about R (a constant = 0.08206). That is a part of the PV = nRT equation but I don't see R anywhere.
(5.08)(V) = 2.00(0.08206)(273+141).
Solve for V. And look to see if you just omitted R in the original post or did the person making the problem omit it? In any event, volume doesn't mean much without that in the equation.

Answer 6

thank you!
but where did 273 come from?

Answer 7

T is 141 C in the problem. In pV = nRT, T is in Kelvin. To convert celsius to Kelvin, the formula is 273 + C = 273 + 141 = 414 K.
