If 3.21 mol of a gas occupies 56.2L at 44C and a pressure of 793 torr, what volume will 5.29 mol of this gas occupy under the same conditions?

Question

(A) 61.7 L
(B) 30.9 L
(C) 14.7 L
(D) 92.6 L
(E) 478 L

Answer 1

Convert degrees C to degrees K.
K = C + 273
Convert torrs to atm.
atm = torrs / 760

Substitute in PV = nRT and solve for V

Answer 2

456

Answer 3

478

Answer 4

Must think of this as a ratio. The conditions are all the same. If 3.21mol occupies 56.2L then 5.29mol occupies X liters.

3.21mol/56.2L=5.29mol/X

Cross multiply and divide.

Ans= 92.6L

Answer 5

93.8 is the correct answer

Answer 6

80.9

Answer 7

v1/n1 = v2/n2
56.2 / 3.21 = v2 / 5.29
v2= 92.6L
