A patient's cardiac output is measured using the Fick's method. The spirometer measures an oxygen content of 32.5 mL for every 225 mL of arterial blood. The spirometer also measures 30 mL of oxygen for every 800 mL of venous blood. If the oxygen uptake is 500 mL/min, find the cardiac output in mL/min.

Matter and Measurement

In the universe, there is matter, energy, and void space. The universe contains energy and void space. The definition of matter can be considered as something which possesses mass and consumes space. Chemistry is that branch of science which deals with the study of matter. Under chemistry, nature, composition, and the changes occurring to matter are discussed.
