<u>Answer:</u>
<em>The number of moles of HCl actually present is 0.000988</em>
<u>Explanation:</u>
<em>The balanced chemical equation of the given reaction is </em>
Here one mole of HCl reacts with one mole of NaOH to form one mole of NaCl and one mole of water. Here the molarity of HCl is given as 0.026M.
<em>molarity of NaOH is 0.032M
</em>
molarity is the number of moles per unit volume of solution.
we have to calculate the number of moles in 36 mL of HCl.
<em>38 mL=36/1000=0.038L
</em>
<em>the number of moles in 38 mL of HCl is given by
</em>
<em>no of moles =</em>

<span>TRUE
The atoms of a chemical element can exist in different types. These are called isotopes. They have the same number of protons (and electrons), but different numbers of neutrons. Different isotopes of the same element have different masses.</span>
