    Yes you have to just multiply 52 with that Avagadro number.. What do you get on solving ??

    b> part hint is : 52 g of He: 1 mole of He = 6.023 * 10^{23} atoms 4 g = 6.023 * 10^{23} atoms Solve it for 52 grams..

    See @ashna : You know atomic mass of He is 4: So: 1 mole of He = \(6.023 \times 10^{23}\)atoms Or 4g = \(6.023 \times 10^{23}\)atoms Here it is 4g.. Look for g here..

    Now I am explaining the third case that is 52 u.. There it was g(grams) and now it is u.. Helium has atomic mass of 4g. But if you write it as 4u, then it means 1 atom only.. I mean to say that 4u implies \(\color{red}{\text{One Atom of Helium}}\) Where as 4g implies \(\color{blue}{{6.023 \times 10^{23} \text{Atoms of Helium= 1 Mole of Helium..}}}\)

    I give you other example: For Carbon the mass is 12. So: \(\color{green}{12g = 6.023 \times 10^{23} \text{Atoms of Carbon}}\) But: \(\color{magenta}{12u \implies \text{1 Atom of Carbon..}}\)
