Which of the following metals will dissolve in ice water? A. lead
B. sodium
C. zinc
D. nickel

I think the answer would be sodium

B: Sodium

Explanation:

Sodium if one attempted to experiment this it will result in that sodium will react violently and be exothermic because that the evolve hydrogen immediately ignites fire (Also I'm sorry if this is all wrong and unhelpful)

explanation:

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.
