(This is a part b question... Part a asked to test and see if the dulong and petit relationship is accurate. (M)(C)=25. )
Part b asks.. (Please answer b)
B). For the use of the equation with molecules rather than atoms, the number 25 should be multiplied by the number of atoms per molecule. Is the value 4.184 joules/g deg. for water consistent with this oversimplified approach? Explain your answer ( note that there is a threshold temperature below which this approach will have a significant error)
What is the molarity of a solution of 14.0 g NH4Br in enough H20 to make 150 ML of solution.
what volume of a 0.37 M Mg(NO3)2 solution contains 87g of Mg(NO3)2.
If the mass of the Co(NO3)2*6H20 obtained to prepare the stock solution had been more than the mass that you recorded would the concentration of the unknowns have been too high
