Answer:
a) Mass of solution is 16,605 milli grams.
b) 57.29 grams is the mass of calcium chloride in 431.3 mL of a 12.0 wt% solution.
c) 1.1967 mol/L is the formal concentration of calcium chloride in 431.3 mL solution.
Explanation:
Mass by mass percentage of calcium chloride solution, wt% = 12.0%
Density of the solution = d = 1.107 g/mL
a) Volume of the solution , V= 15.0 mL
Mass of the solution = m


Mass of solution = 16.605 g = 16,605 mg (1g = 1000 mg)
b) Mass of the solution = m
Volume of the solution = V = 431.3 mL


Mass of calcium chloride = x
w% = 12.0%


57.29 grams is the mass of calcium chloride in 431.3 mL of a 12.0 wt% solution.
c) Moles of calcium chloride = 

V = Volume of the solution in Liters
n = 0.5161 mole
V = 431.3 mL = 0.4313 L

1.1967 mol/L is the formal concentration of calcium chloride in 431.3 mL solution.

Cellular Respiration is the process of the release of energy from food. Hence, option B is correct.
<h3>What is cellular respiration?</h3>
Cellular respiration is the process by which organisms use oxygen to break down food molecules to get chemical energy for cell functions.
Through the process of cellular respiration, the energy in food is converted into energy that can be used by the body's cells. During cellular respiration, glucose and oxygen are converted into carbon dioxide and water, and the energy is transferred to ATP.
Hence, option B is correct.
