Explanation: (2) Remember at STP a mole of gas occupies 22.4 liters. Density = mass / volume or M = D x V Substitute: 0.63 g for mass and multiply by 22.4 L to find the answer. 0.63 g x 22.4 L = 14.1 g. 21. The heat of fusion of a compound is 30 joules per gram.

From Table 1, this RQ value (left column) corresponds to an energy equivalent of 4.875 kCal per liter of oxygen uptake, or an energy output of 15.7 kCal•min–1 (2.78 L O2•min–1 x 4.875 kCal). Based on a non-protein RQ, 54.1% of the calories come from the combustion of carbohydrate and 45.9% from fat.

A mole of ideal gas contains 6.02x1023 molecules and occupies 22.4 liters at STP. In a mixture of gases the total pressure is the sum of the partial pressures of the components. According to Graham's law of diffusion, gases with larger molecular weights diffuse through small openings more rapidly than gases with smaller molecular weights.

Similarly, if the patient is being evaluated for lung resection, you like them to end up with an FEV1 > 0.8 or 1.0 liters. Therefore, a patient with an FEV1 of 1.2 liters would be very high risk for a pneumonectomy (predicted post-op FEV1 = 0.6 L) but only moderate risk for a lobectomy (predicted post-op FEV1 = 1.0 L).

The last adjustment of N2O should be made when the oxygen and the nitrous oxide are each at 4 liters, again totaling 8 liters. At this point, 50 percent O2 and 50 percent N2O are being administered. This is the highest ratio of nitrous oxide recommended for safe administration without special consideration.

Make a semi-quantitative design for a flotation saturation chamber, given that the mass concentration of nitrogen and oxygen in water from air at atmospheric pressures equals about 15 mg/L and 10 mg/L, respectively. The gas requirements for flotation amount to about 10 mg/L (excess). Suitable air compressors can deliver air at 700 kPa.

Because the average adult’s total blood volume equals about 5 liters, 15 mL of oxygen dissolve for transport in the fluid portion of the blood (3 mL per L x 5 = 15 mL). This amount of oxygen could sustain life for only about four seconds. Viewed from a different perspective, the body would need to circulate 80 liters of blood each minute just ...
