Answer:

B. requires oxygen.

Explanation:

Respiration is the aerobic break down of glucose to make energy. Aerobic means that it requires oxygen to occur. Fermentation on the other hand is the anaerobic break down of glucose to make energy. The only difference is that fermantation happens in the absence of oxygen

A 23.6 g sample of NagPO4 (molar mass 163.94 g/mol) is dissolved in enough water to produce

Gnom [1K]

Taking into account the definition of molarity, the concentration of Na₃PO₄ in solution is 0.192 $\frac{moles}{lliter}$ .

<h3>Definition of molarity</h3>

Molar concentration or molarity is a measure of the concentration of a solute in a solution and indicates the number of moles of solute that are dissolved in a given volume.

The molarity of a solution is calculated by dividing the moles of solute by the volume of the solution:

$Molarity=\frac{number of moles}{volume}$

Molarity is expressed in units $\frac{moles}{lliter}$ .

<h3>Concentration of Na₃PO₄ in solution</h3>

Being the molar mass of Na₃PO₄ 163.94 g/mole, that is, the amount of mass that a substance contains in one mole, the amount of moles that contains 23.6 g sample of Na₃PO₄ is calculated as:

$23.6 gramsx\frac{1 mole}{163.94 grams} = 0.144 moles$
