Question

Make the indicated pressure conversions.

(a) 612 mm Hg to torr
torr

(b) 11.6 psi to mm Hg
mmHg

(c) 857 mm Hg to psi
psi

(d) 779 mm Hg to atmospheres

atm

portion 2 For each of the following sets of pressure/volume data, calculate the new volume of the gas sample after the pressure change is made. Assume that the temperature and the amount of gas remain the same.

(1) V = 110. mL at 727 mmHg; V = WebAssign will check your answer for the correct number of significant figures. mL at 711 mmHg

(2) V = 231 mL at 1.00 atm; V = WebAssign will check your answer for the correct number of significant figures. mL at 0.902 atm

(3) V = 3.28 L at 104 kPa; V = WebAssign will check your answer for the correct number of significant figures. L at 115 kPa

Answer 1

(a)

$\text { 612 mm Hg } \times \frac{\text { 1 torr }}{\text { 1 mm Hg }}=\text { 612 torr}$

(b)

$\text { 11.6 psi } \times \frac{\text { 51.715 mm Hg }}{\text { 1 psi}}=\text { 599.9 mm Hg} \simeq \text { 600. mm Hg}$

(c)

$\text { 857 mm Hg } \times \frac {\text { 1 psi}}{\text { 51.715 mm Hg }}=\text { 16.6 psi}$

(d)

$\text { 779 mm Hg } \times \frac {\text { 1 atm}}{\text { 760 mm Hg }}=\text { 1.03 atm}$
