[3] Anhydrous sodium sulfate can absorb water vapor and be converted to the decahydrate. By how many grams would the mass of a 1.00 gram sample of the
anhydrous compound increase if exposed to enough water to produce the
decahydrate?

If the mass of the products measured 120g what would the mass of the reactants a. 30g b. 60g c. 120g d. 240g

Abeaker with 2.00×102 ml of an acetic acid buffer with a ph of 5.000 is sitting on a benchtop. the total molarity of acid and conjugate base in this buffer is 0.100 m. a student adds 4.70 ml of a 0.360 m hcl solution to the beaker. how much will the ph change? the pka of acetic acid is 4.740.
