Calculate the number of atoms in . (a) 52 moles of he. (b) 52 g of he. (c) 52 u of he

Atomic mass of Helium is 4u = 2protons + 2 Neutrons = 1 atom 
No. of atoms in 52u = 52/4 = 13 atoms

52g of heliume
6.022*10^23*52/4 atoms of he
7.829*10^24 atoms of he

1mole of he =6.023*1023

I’d have to say no because without oxygen in the water the fish would all be dead. so if you want to fish for dead fish, pick the ponds with the lowest oxygen concentrations.
