Answer:

0.35 M

Explanation:

Molar mass of calcium chloride= 40+2(35.5)= 111gmol-1

Mass calcium chloride= 21.84g

Volume of solution= 562.43ml

From

n= CV

But n=m/M

n= number of moles

C=concentration

V= volume of solution in litres

m=mass of substance

M= molar mass of substance

n=21.84/111= 0.197moles

C= 0.197 ×1000/562.43

C= 0.35 M

How do cells get ATP, the energy currency that does work in living things?
luda_lava [24]
How do cells get ATP through Cellular Respiration.
Cellular respiration takes place in the mitochondria. The Mitochondria use oxygen (O2) to convert broken-down glucose (at type of sugar) into carbon dioxide (CO2) and water (H2O).
The reactants of CR are oxygen and glucose.
The products of CR are ATP, carbon dioxide, and water.
