molar mass of Na =23
23g=1 mole
therefore 46g=2 mole.
1 mole contains 6.022×10^23 particles
therefore 2 mole will contain 2×6.022×10^23
=12.044×10^23 particles.

molar mass of O2=32
32g =1 mole
therefore 8g=1/4 mole
1 mole contains 6.022×10^23 particles
therefore 1/4 mole contains=(6.022×10^23)/4
=1.5055×10^23 particles.

1 mole contains 6.022×10^23 particles
0.1 mole of carbon contains=(6.022×10^23)/0.1
=6.022×10^22 particles
