Answer: 20.4752789138x x 10^23 atoms
To count how many atoms in moles you need to know Avogadro's number. Avogadro's number dictate that for every mole there is 6.022140857 × 10^23 molecule/atoms.
Then 3.4 moles of helium will be 3.4x 6.022140857 x 10^23 atoms= 20.4752789138x x 10^23 atoms

Answer:

work done on the object by gravitational force = 0 joules

Explanation:

work = force × displacement

force = mass × acceleration

so,

work = mass × acceleration × displacement

we know that mass= 10 kg , gravitational acceleration= 9.8 $m/s^2$

and displacement= 0 m since the object is not moving vertically.

so,

work = 10 × 9.8 × 0 = 0 joules
