A 6.00−g quantity of a diprotic acid was dissolved in water and made up to exactly 200 mL. Calculate the molar mass of the acid if 25.0 mL of this solution required 10.3 mL of 1.00 M KOH for neutralization. Assume that both protons of the acid were titrated.

What happened in 2012 and how does it illustrate the importance of understanding the sun and how it works?

Using data from seismic waves, geologists have learned that earth’s interior is made up of several

Acalorimeter is to be calibrated: 51.203 g of water at 55.2 degree c is added to a calorimeter containing 49.783 g of water at 23.5c. after stirring and waiting for the system to equilibrate, the final temperature reached is 37.6 degree c. specific heat capacity of water (s = 4.18 j/g∙degree c). calculate the calorimeter constant. (smδt)warm water = -[(smδt)cold water + (calorimeterδtcold water)]
