Answer 1

1 atm = 760 torr = 10332.276 mm H₂O

V(ml)	P (mm H2O)	1/P (1/mm H2O)	PV (mm H2O *mL)
30	10332.276	0.00009678	309968.28
25	10343.276	0.00009668	258581.9
20	10351.776	0.00009660	207035.52
15	10357.276	0.00009655	155359.14
10	10366.776	0.00009646	103667.76
5	10372.776	0.00009641	51863.88

PV from graph = 6.67x10⁷ mmH₂O x mL

V vs 1/P - V(ml) = 6.67E+07*x + -6426 V (ml) 0.00009645 0.00009650 0.00009655 0.00009660 0.00009665 0.00009670 0.00009675 1/P (1/mm H20)
