Answer:
The answer is
<h2>686.01 g</h2>
Explanation:
The mass of a substance when given the density and volume can be found by using the formula
<h3>mass = Density × volume</h3>
From the question
volume of zinc = 96.08 cm³
density = 7.14 g/cm³
The mass is
mass = 96.08 × 7.14 = 686.0112
We have the final answer as
<h3>686.01 g</h3>
Hope this helps you
1 mole Zn ---------- 6.02 x 10²³ atoms
0.750 moles Zn ----- ?
atoms = 0.750 * ( 6.02 x 10²³ / 1 )
= 4.515 x 10²³ atoms
hope this helps!
Answer:The process by which dissolved gases are exchanged between the blood and interstitial fluids is called internal respiration.
Explanation:
Physiologically respiration is defined as the passing of oxygen the external environment into the cells within tissues, and the transport of carbon dioxide in the opposite direction.
Respiration is divided into three:
1.) The external respiration: this involves the inhalation of air and exhalation of used gases.
2.) The internal respiration: this is defined as a process of diffusing oxygen from the blood, into the interstitial fluid and into the cells
3.) Cellular respiration: this involves the conversion of food to energy. Its further divided into aerobic respiration, which is a cellular respiration that requires oxygen and anaerobic respiration which does not.
