Calculate the mass of 1.23×1024 helium atoms.

6.023*1023 He atoms=1 mole He

1.23×1024 helium atoms=1.23×1024/6.023*1023 =2.042 mole He

one mole He=4.0 gm

2.042 mole He=2.042*4.0=8.168 gm

answer in grams of Helium is 8.168 gm

if you're asking what comes out, it's steam.

it should have an internal chamber and two thermometers sticking out of the top. the internal chamber will also be closed off from the outside.
