Can someone help with these dilutions, and please write out your answers and explain each step thank you!

To prepare 4 mL of 1.0 M stock HCl solution, dilute 37% (w/w) HCl (MW = 36.46 g/mol, d = 1.18 g/mL at 25C) with 10% D2O (i.e., 90% H2O) stock solution. Remember to add acid to water as the reaction is highly exothermic.

2. To prepare 4 mL of 1.0 M KOH stock solution, measure the mass of two KOH pellets (MW = 56.11 g/mol). Calculate the volume of 10% D2O required and dissolve the pellets with 10% D2O stock solution. Make sure the pellet is completely dissolved. Properly label each solution.
