Washing soda is a form of a hydrated sodium carbonate (Na2CO3 ∙ 10H2O). If a 10g sample was heated until all the water was driven off and only 3.65 g of anhydrous sodium carbonate (106 g/mol) remained, what is the percent error in obtaining the anhydrous sodium carbonate?
Na2CO3 ∙ 10H2O → Na2CO3 + 10H2O
a
0.16%
b
1.62%
c
3.65%
d
2.51%

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 23.5c. 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)]
