1) Show the calculation for determining the mass of NaOH pellets required to prepare 250mL of 0.10M NaOH.

0.10M NaOH = 0.10 moles/litre

Since 250 mL = 0.250 litres, we can calculate the total # of moles required for the solution:

(0.10 moles/litre)(0.250 litres) = 0.025 moles

Now, all we need is the molar mass of NaOH. From the periodic table, we get the ...
