2.65g of anhydrous sodium trioxocarbonate (IV) were dissolved in water and makes up to 250^3 of hydrochloric acid for complete neutralization. (1) the concentration of sodiumtriococarbonate(IV) in g/moldm^3 (2) the concentration of sodiumtriococarbonate (IV) in mol/dm^3​

How to convert a density of 0.791g/cm3 to lb/ft3

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)]
