Is there a picture or something? i cant see it.
The correct answer to this is:
<span>Chondroitin sulfate is abundant in the matrix of <u>“Cartilage”.</u></span>
<span>A 1 unit of Chondroitin sulfate has a chemical formula of
C</span>13H21NO15<span>S. It is
usually found attached to proteins as part of a proteoglycan and is a vital
structure of cartilage by providing much resistance to compression. Due to
this, this chemical has found wide use as a dietary supplement for treatment of
osteoarthritis.</span>
According to the balanced chemical equation:
4 HPO₃ + 12 C → 2 H₂ + 12 CO + P₄
4 moles of HPO₃ ---gives---> 12 moles of CO
2.73 moles of HPO₃ ---gives---> ? moles of CO
so number of moles of CO =

= 8.19 moles of CO
Number of molecules of CO = number of moles * Avogadro's number
= 8.19 * (6.022 * 10²³) = 4.93 * 10²⁴ molecules
