This can be solved with a simple stoichiometry equation.

The molar mass of He is 4.00 g/mol.

With the equation

Mass=Moles*Molar mass,

we can solve this very easily.

Rearraging the equation gives us

Mass/Molar Mass=Moles

Plugging in our variables:

(534,000g)/(4g/mol)=Moles

this gives us a total of 133 500 moles.

Multiplying 133 500 moles by Avagadro's constant (6.022x10^23) to give us the number of atoms leaves us with the answer:
