anonymous · Answer

haha no! this is why im so conufused. I found the mass, ( i thought ) which was 18.02 then converted it to g which is 0.0180kg but i dont know where 112kg came from...

anonymous · Answer

can you go from moles to mass?

aaronq · Answer

yes you can if you have the number of moles you can multiply it by the molecular mass (which for oxygen is 18g/mol) and get the mass

anonymous · Answer

okay

aaronq · Answer

but really if they just said find the mass of H2O, thats impossible, they have to give you more parameters
