Answer to Question 1

ANS: B
One liter of oxygen weighs 2.5 lb. 2.5 lb  16 oz/lb = 40 oz.

Answer to Question 2

ANS: A
First subtract 8 lb from 30 lb = 22 lb. Convert 22 lb/2.5 lb/L = 8.8 L. 8.8 L  860 (liter of liquid oxygen multiplied by 860 equals the liters of gaseous oxygen) = 7568 L. Then divide by liter flow. 7568/3 L/min = 2522 min = 1 day 18 hours.
