1) if 6.85 of glucose( C6H12O6, molar mass=180.2 g/mol) is dissolved in 155g of chloroform( CHCL3,molar mass= 119.4 g/mol) , what is the boiling point of the solution. ( the boiling point of pure CHCl3 is 61.2 celsius, and Kb = 3.63 celsius/m for CHCl3)
2) a,) Liquid ammonia (boiling point = -33.4C) can be used as a
refrigerant and heat transfer fluid. How much energy is needed to
heat 25.0 g of NH3(l) from -65.0C to -12.0C? Heat of vaporization:
23.5 kJ/mol
Specific heat capacity, NH3(l): 4.7 J/(g*k), Specific heat
capacity, NH3(g): 2.2 J/(g*k)
Can you write down formula and explain step by step pls?
