When 25.0 mL of 1.0 M H2SO4 is added to 50 ml of 1.0 M NaOH at 25 oC in a calorimeter, the temperature of the aqueous solution increases to 29.9 oC. Calculate the DH (in kJ) for the reaction. Assume the calorimeter absorbs no heat.

number of molecules / avogadro's number * molecule molecular = mass

explanation:

we define a gram-molecular weight as the mass of one mole of any element or compound. a mole contains avogadro's number of units (molecules) –  

6.022

x

23

. so, dividing the number of molecules by avogadro's number gives us the number of moles. multiplying that by the molecular weight gives us the mass. from the periodic table we find the gram-molecular weight of u to be238 and of f to be19. so,  

u

f

will have a gram-molecular weight of 352g.

here are some of the ways in which chemical and nuclear reactions differ.
