Finding rate of oxygen consumption

In summary, the actual rate of oxygen consumption (ml/min/g @ STP) is 0.8, calculated using the specific rate of oxygen consumption of 8.2 ml/min/g, a room temperature of 21 C, and an atmospheric pressure of 76 mm of Hg. This was determined using the equation (P1V1)/T1, where V1 is the specific rate of oxygen consumption, T1 is the temperature in Kelvin, and P1 is the atmospheric pressure.

Homework Statement


Calculate the actual rate of oxygen consumption (ml/min/g @ STP) to one decimal place from the following information:
Specific rate of oxygen consumption: 8.2 ml/min/g
Temperature of room: 21 C
Atmospheric Pressure of room: 76 mm of Hg

a. 0.4
b. 0.6
c. 0.8


Homework Equations



(P1V1)/T1
V1 is the 8.2 ml/min/g
T1 = 21 + 273 = 294
P1= 76 mm of Hg

The Attempt at a Solution



Following the equation, I get 2.12, which is not one of the answers...

Thanks for helping me..

Actually, I did the following and found an answer similar to what we are given.
Would that be correct?
(21*273*8.2)/(760*76)=0.8.

Don't worry about it, it was the correct answer :)
 

1. What is the purpose of finding the rate of oxygen consumption?

The purpose of finding the rate of oxygen consumption is to measure the amount of oxygen used by an organism or a system in a given time period. This measurement can provide valuable information about the metabolic activity and energy production of the organism or system.

2. How is the rate of oxygen consumption measured?

The rate of oxygen consumption can be measured using a variety of techniques, such as respirometry, mass spectrometry, or polarography. These techniques involve measuring the change in oxygen levels over time, either directly or indirectly, to determine the rate of consumption.

3. What factors can affect the rate of oxygen consumption?

The rate of oxygen consumption can be influenced by a number of factors, including the type and size of the organism or system, the level of physical activity, the availability of oxygen, and environmental conditions such as temperature and pH.

4. Why is it important to accurately measure the rate of oxygen consumption?

Accurately measuring the rate of oxygen consumption is important because it can provide insight into the overall health and functioning of an organism or system. It can also be used to compare the metabolic rates of different organisms or to track changes in metabolic activity over time.

5. Can the rate of oxygen consumption be used to make predictions?

Yes, the rate of oxygen consumption can be used to make predictions about an organism's energy needs and its ability to adapt to changing conditions. It can also be used to predict the effects of environmental stressors or to assess the efficiency of different metabolic processes.
