1. " Calculate the number of moles of acetic acid that were present in the original buffer solution prepared. Assume no change in volume upon addition of sodium acetate trihydrate. Discuss this calculation."

2. " Calculate the number of moles of acetate that were present in the original buffer solution prepared. The molecular mass of sodium acetate trihydrate is 136.08 g/mol. Discuss this calculation."

I prepared 30mL of 0.25M acetic acid by combining 1.020 g solid sodium acetate trihydrate and 15 mL DI H2O as well as 15 mL of stock 0.5 M acetic acid. Just don't know how to calculate the number of moles of acetic acid or acetate.
