<span>Mole ratios are important to stoichiometric calculations because they bridge the gap when we have to convert between the mass of one substance and the mass of another.</span>
Answer:
<em>Lower vapor pressures of a substance has an obvious effect on a</em> <em>boiling point</em>. <em>The</em> <em>freezing point </em><em>the rate at which the solid melts is equal to the rate which freezes. </em>
Explanation:
<em>In practice, small differences between these quantities can be observed. It is difficult, if not impossible, to heat a solid above its melting point because the heat </em>

Answer:
25.6mL NaOH
Explanation:
We are given the Molarity of the solution (
) and the volume of the solution (.02L).
By multiplying the two together, we can find the moles of solution that are reacted with HCl.

This gives us .0082 moles of HCl.
We then find the moles of NaOH that are needed to react with the HCl using the equation.

As HCl and NaCl have a 1:1 ratio, we need .0082 mol of NaOH.
Dividing this value by the Molarity of the solution

Gives us the answer, in Liters (.0256), which we can then divide by 100 convert to mL.
