The molarity of the NaCl in the 250 ml slat solution is 2.8M.
<h3>What is molarity?</h3>
The molarity of a solution is defined as the concentration of a solute per unit volume of the solution.
Given, the volume of the solution is 250 ml converted into l 0.25
The number of moles of NaCl is 0.70.
By the formula of molarity
Thus, the molarity is 2.8 M.

Answer:
At this partial pressure of oxygen, Mb would be almost completely saturated but Hb would not.
Explanation:
The oxygen saturation curves for Mb and Hb are quite different. The curve for Mb is hyperbolic while that for Hb is sigmoidal.
Mb reaches oxygen saturation before Hb.
Thus, at a partial pressure of 40 mmHg, Mb is almost completely saturated but Hb is not.
