Answer:
Water serves to suspend the red blood cells to carry oxygen to the cells. It is the solvent for the electrolytes and nutrients needed by the cells, and also the solvent to carry waste material away from the cells. With water as the solvent, osmotic pressure acts to transport the needed water into cells.
Explanation:
The ZnCl₂ solution have a molarity of 1.33 M.
Explanation:
We have the following chemical reaction:
Zn (s) + CuCl₂ (aq) → ZnCl₂ (aq) + Cu (s)
number of moles = mass / molar weight
number of moles of Zn = 25 / 65.4 = 0.38 moles
From the chemical equation we see that 1 moles of Zn produces 1 mole of ZnCl₂, so 0.38 moles of Zn will produce 0.38 moles of ZnCl₂.
molarity = number of moles / volume (L)
molarity of the ZnCl₂ solution = 0.38 / 0.285 = 1.33 M
