Nitric acid reacts with insoluble copper(ii) oxide to form soluble copper(ii) nitrate, cu(no3)2, a compound that has been used to prevent the growth of algae in swimming pools. write the balanced chemical equation for the reaction of an aqueous solution of hno3 with cuo. (include states-of-matter under the given conditions in your answer. use the lowest possible whole number coefficients.)

Explanation:

CuO(s) + 2HNO3(l)  > Cu(NO3)2(l)  + H2O(l).

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

10

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

6

will have a gram-molecular weight of 352g.
